Description

本発明は、加工システム及び加工方法に関し、特に、ワークの表面形状の誤差補正を行って加工を行う加工システム及び加工方法に関する。   The present invention relates to a machining system and a machining method, and more particularly, to a machining system and a machining method for performing machining by correcting an error of a surface shape of a workpiece.

既知の位置にある基準点によって、全体的な座標系におけるセンサユニットの位置を決定し、センサユニットが有するスキャナユニットからの測定対象のデータを全体的な座標系に変換する技術が知られている（特許文献１参照）。   A technique is known in which the position of a sensor unit in an overall coordinate system is determined by a reference point at a known position, and data to be measured from a scanner unit included in the sensor unit is converted into an overall coordinate system. (See Patent Document 1).

特表２００３−５０５８６２号公報JP-T-2003-505862

鋳物素材等のワークには成形誤差があり、精密鋳造法でワークを鋳造したとしても、±０．５ｍｍ程度の成形誤差がでる。そのようなワークに対して加工を行う場合、成形誤差を考慮して加工を行わないと、最終的な製品の加工精度がでない、加工品質が悪いという問題が起こるおそれがある。例えば、レーザ加工機を用いて加工を行う場合には、焦点誤差を±０．１ｍｍ以内に抑える必要があるが、上述した鋳物素材等のワークでは、その成形誤差によりレーザの焦点が合わなくなり、そのため、加工径が大きくなる、酸化層が増える、だれが起こる、焼きすぎる等の加工精度、加工品質の問題が起こりうる。   A work such as a casting material has a forming error, and even if the work is cast by a precision casting method, a forming error of about ± 0.5 mm is generated. When processing such a workpiece, if the processing is not performed in consideration of forming errors, there may be a problem that the processing accuracy of the final product is not good and the processing quality is poor. For example, when performing processing using a laser processing machine, it is necessary to suppress the focus error to within ± 0.1 mm, but in the workpiece such as the casting material described above, the laser is not focused due to the forming error, For this reason, problems such as processing accuracy and processing quality such as an increase in the processing diameter, an increase in the number of oxide layers, occurrence of wrinkles, and excessive baking may occur.

なお、特許文献１に記載の技術を用いることにより、ワーク自体の成形誤差を測定することは可能であるが、測定した成形誤差を加工装置で使用するためには、座標変換等の工夫が必要であり、そのままでは使用することはできない。又、加工装置で使用するための座標変換の際には、その座標変換の計算が煩雑になると共に、計算誤差が生じるおそれもある。   In addition, it is possible to measure the forming error of the workpiece itself by using the technique described in Patent Document 1, but in order to use the measured forming error in the processing apparatus, a device such as coordinate conversion is required. It cannot be used as it is. Further, when coordinate conversion for use in a processing apparatus is performed, calculation of the coordinate conversion becomes complicated and a calculation error may occur.

本発明は上記課題に鑑みなされたもので、ワークの表面形状の誤差補正を行うことができる加工システム及び加工方法を提供することを目的とする。   The present invention has been made in view of the above problems, and an object thereof is to provide a machining system and a machining method capable of correcting an error in the surface shape of a workpiece.

Here, as an example of the processing apparatus, a laser processing machine is illustrated, but the present invention is also applicable to other processing apparatuses.

［実施例１］
最初に、図１を参照して、本実施例の加工システムの構成を説明する。本実施例の加工システムは、Ethernet（登録商標）等のネットワーク１０を介して、加工マスタデータＰＣ（以降、マスタＰＣ）１２とデータベースサーバＰＣ（以降、サーバＰＣ）１４と３次元計測装置２０とレーザ加工機３０とが互いに通信可能に接続された構成である。なお、サーバＰＣ１４は、設計データ用の記憶装置として機能し、ここでは、３次元計測装置２０やレーザ加工機３０と独立して設けているが、３次元計測装置２０やレーザ加工機３０に記憶装置を設け、当該記憶装置をサーバＰＣ１４の代わりに使用しても良い。 [Example 1]
Initially, with reference to FIG. 1, the structure of the processing system of a present Example is demonstrated. The machining system of the present embodiment includes a machining master data PC (hereinafter referred to as master PC) 12, a database server PC (hereinafter referred to as server PC) 14, and a three-dimensional measuring device 20 via a network 10 such as Ethernet (registered trademark). The laser processing machine 30 is connected to be communicable with each other. The server PC 14 functions as a storage device for design data. Here, the server PC 14 is provided independently of the three-dimensional measurement device 20 and the laser processing machine 30, but is stored in the three-dimensional measurement device 20 and the laser processing machine 30. A device may be provided and the storage device may be used instead of the server PC 14.

マスタＰＣ１２は、ＣＡＤ／ＣＡＭ（Computer Aided Design/Computer Aided Manufacturing）用のコンピュータであり、設計データとして、加工対象のワークＷの表面形状を表すワーク表面形状データと共に、ワークＷを加工するための加工制御用データを作成するものである。ここでは、加工制御用データとして、ワークＷに対するレーザ加工機３０による穴開け加工の加工制御用データが予め作成されている。   The master PC 12 is a computer for CAD / CAM (Computer Aided Design / Computer Aided Manufacturing), and the processing for processing the workpiece W together with the workpiece surface shape data representing the surface shape of the workpiece W to be processed as design data. It creates control data. Here, as the processing control data, processing control data for drilling the workpiece W by the laser processing machine 30 is created in advance.

マスタＰＣ１２においては、所定の空間座標におけるワーク表面形状データ及び加工制御用データを予め作成している。ここで、図３（ａ）、（ｂ）を参照して、所定の空間座標について説明する。この所定の空間座標とは、３つの基準支柱５２を有する基準治具５０にワークＷを所定の位置及び姿勢で設置する場合において、３つの基準支柱５２の所定箇所（例えば、それらの上面の中心）により形成される座標基準面５３を基準とする空間座標のことである。この所定の空間座標を基準点座標とし、後述するように、３次元計測装置２０やレーザ加工機３０でも用いている。   In the master PC 12, workpiece surface shape data and machining control data at predetermined spatial coordinates are created in advance. Here, predetermined spatial coordinates will be described with reference to FIGS. The predetermined spatial coordinates refer to predetermined locations (for example, the centers of the upper surfaces of the three reference columns 52) when the workpiece W is set in a predetermined position and posture on the reference jig 50 having the three reference columns 52. ) Is a spatial coordinate based on the coordinate reference plane 53 formed by the above. The predetermined spatial coordinates are used as reference point coordinates, and are also used in the three-dimensional measuring apparatus 20 and the laser processing machine 30 as described later.

上述した基準治具５０は、具体的には、平板状の基台５１と、基台５１の上面に設けられた３本の円柱状の基準支柱５２とからなり、基台５１の上面がワークＷを設置する設置基準面５４となっている。基準支柱５２は、少なくとも３本あれば良いが、好ましくは４本又は５本あれば、後述する３次元計測装置２０及びレーザ加工機３０での計測の際に、その計測誤差を低減することができる。   Specifically, the above-described reference jig 50 includes a flat base 51 and three columnar reference columns 52 provided on the upper surface of the base 51, and the upper surface of the base 51 is a workpiece. An installation reference plane 54 for installing W is provided. There may be at least three reference struts 52, but preferably four or five reference struts 52 can reduce measurement errors during measurement by the three-dimensional measuring device 20 and the laser processing machine 30 described later. it can.

マスタＰＣ１２では、ワークＷの基準治具５０への仮想的な設置を想定している。これは、ワークＷの基準治具５０への実際の設置と同一である。即ち、ワークＷ自体には通常加工基準面が設定されているので、ワークＷの加工基準面を基準治具５０の設置基準面５４に設置し、基準支柱５２やクランプなどにより、ワークＷの位置がずれないようにすれば、所定の位置及び姿勢でワークＷを基準治具５０に実際に設置することになる（図３（ａ）、（ｂ）参照）。マスタＰＣ１２では、これと同一の位置及び姿勢でワークＷを基準治具５０へ仮想的に設置した場合を想定して、上記データを作成している。   In the master PC 12, it is assumed that the workpiece W is virtually installed on the reference jig 50. This is the same as the actual installation of the workpiece W on the reference jig 50. That is, since the normal processing reference surface is set for the workpiece W itself, the processing reference surface of the workpiece W is set on the setting reference surface 54 of the reference jig 50, and the position of the workpiece W is determined by the reference support 52 or the clamp. If it does not shift, the workpiece W is actually placed on the reference jig 50 at a predetermined position and posture (see FIGS. 3A and 3B). The master PC 12 creates the above data assuming that the workpiece W is virtually installed on the reference jig 50 at the same position and posture.

再び、図１を参照すると、マスタＰＣ１２で作成されたワーク表面形状データ及び加工制御用データは、ネットワーク１０を介して、サーバＰＣ１４へ送られる。サーバＰＣ１４は、ワーク表面形状データ及び加工制御用データと共に、後述するギャップデータを保存する。このサーバＰＣ１４は、加工情報管理システムとして機能し、レーザ加工機３０は、ギャップデータ、加工制御用データなどを参照して、ワークＷを加工することになる。   Referring to FIG. 1 again, the workpiece surface shape data and machining control data created by the master PC 12 are sent to the server PC 14 via the network 10. The server PC 14 stores gap data, which will be described later, together with workpiece surface shape data and machining control data. The server PC 14 functions as a processing information management system, and the laser processing machine 30 processes the workpiece W with reference to gap data, processing control data, and the like.

３次元計測装置２０は、３次元スキャナ２１と計測ＰＣ２２（演算手段）とを有する。なお、この計測ＰＣ２２に代えて、シーケンサでも良い。３次元計測装置２０では、計測ＰＣ２２により３次元スキャナ２１を制御しており、基準治具５０に所定の位置及び姿勢で設置したワークＷに対し、基準治具５０と共に３次元計測を行っている。   The three-dimensional measurement apparatus 20 includes a three-dimensional scanner 21 and a measurement PC 22 (calculation means). Note that a sequencer may be used instead of the measurement PC 22. In the three-dimensional measurement apparatus 20, the three-dimensional scanner 21 is controlled by the measurement PC 22, and three-dimensional measurement is performed together with the reference jig 50 on the workpiece W placed at a predetermined position and posture on the reference jig 50. .

詳細は後述するが、３次元計測装置２０は、３次元計測により基準治具５０の基準支柱５２を位置認識し、３次元計測装置２０における基準点座標を規定した後、３次元計測によるワーク表面形状データを基準点座標に座標変換し、その後、座標変換したワーク表面形状データとサーバＰＣ１４に保存してあるワーク表面形状データとの差を比較して、ギャップデータを求めている。ここで求めたギャップデータも、ネットワーク１０を介して、サーバＰＣ１４へ送られて、保存されることになる。   Although the details will be described later, the three-dimensional measuring device 20 recognizes the position of the reference column 52 of the reference jig 50 by three-dimensional measurement, defines the reference point coordinates in the three-dimensional measuring device 20, and then the workpiece surface by three-dimensional measurement. The shape data is converted into reference point coordinates, and then the difference between the coordinate-converted workpiece surface shape data and the workpiece surface shape data stored in the server PC 14 is compared to obtain gap data. The gap data obtained here is also sent to the server PC 14 via the network 10 and stored.

レーザ加工機３０は、ハブ３１と、操作パネル３２と、制御ユニット３３（制御手段）と、レーザ発振器３４と、加工ヘッド３５と、センサ３６とを有している。これら機器同士は、直接又はハブ３１を介して、互いに通信可能に接続されている。ユーザは、操作パネル３２によりレーザ加工の条件等を設定し、制御ユニット３３は、設定された条件に基づいて、レーザ発振器３４及び加工ヘッド３５を制御して、基準治具５０に所定の位置及び姿勢で設置したワークＷに対し、レーザ加工を行うことになる。なお、センサ３６としては、対象物の位置認識ができれば、上述した３次元スキャナのようなものでも良いし、他のものでも良い。   The laser processing machine 30 includes a hub 31, an operation panel 32, a control unit 33 (control means), a laser oscillator 34, a processing head 35, and a sensor 36. These devices are communicably connected to each other directly or via the hub 31. The user sets the laser processing conditions and the like using the operation panel 32, and the control unit 33 controls the laser oscillator 34 and the processing head 35 based on the set conditions, so that the reference jig 50 has a predetermined position and Laser processing is performed on the workpiece W installed in the posture. Note that the sensor 36 may be a three-dimensional scanner as described above or may be another sensor as long as the position of the object can be recognized.

詳細は後述するが、レーザ加工機３０は、ワークＷの形状誤差を補正するため、センサ３６により基準治具５０の基準支柱５２を位置認識し、レーザ加工機３０における基準点座標を規定した後、サーバＰＣ１４に保存してある加工制御用データ及びギャップデータを参照して、加工制御用データをギャップデータで補正しており、補正後の加工制御用データを用いることにより、ワークＷの形状誤差を補正して、ワークＷのレーザ加工を行っている。   Although details will be described later, after the laser processing machine 30 recognizes the position of the reference column 52 of the reference jig 50 by the sensor 36 and defines the reference point coordinates in the laser processing machine 30 in order to correct the shape error of the workpiece W. The machining control data and the gap data stored in the server PC 14 are referred to, and the machining control data is corrected with the gap data. By using the corrected machining control data, the shape error of the workpiece W is obtained. Is corrected and laser processing of the workpiece W is performed.

次に、上述した加工システムにおける加工方法について、図１と共に、図２、図３（ａ）、（ｂ）及び図４も参照して説明する。なお、図４は、図３（ｂ）におけるワークＷのＸ軸方向の断面の表面部分に該当する。   Next, a processing method in the above-described processing system will be described with reference to FIGS. 2, 3A, 4B, and 4 together with FIG. FIG. 4 corresponds to the surface portion of the cross section in the X-axis direction of the workpiece W in FIG.

（ステップＳ１）
３本の基準支柱５２を有する基準治具５０に加工対象のワークＷを所定の位置及び姿勢で設置する場合について、３本の基準支柱５２の所定箇所、例えば、それらの上面の中心により形成される座標基準面５３を基準とする基準点座標でのワーク表面形状データ及び加工制御用データをマスタＰＣ１２で予め作成する。 (Step S1)
In the case where the workpiece W to be machined is set in a predetermined position and posture on a reference jig 50 having three reference columns 52, it is formed by a predetermined portion of the three reference columns 52, for example, the center of the upper surface thereof. Work surface shape data and processing control data at reference point coordinates with reference to the coordinate reference surface 53 to be created in advance by the master PC 12.

基準点座標については、まず、図３（ａ）に示すように、３本の基準支柱５２の上面の中心により、座標基準面５３を設定し、次に、図３（ｂ）に示すように、３本の基準支柱５２の上面の中心を通る軸線を設定し、これにより、原点及びＸＹＺ軸を決め、原点及びＸＹＺ軸からなる直交座標を設定することにより、基準点座標となる空間座標を設定する。   As for the reference point coordinates, first, as shown in FIG. 3A, the coordinate reference plane 53 is set by the center of the upper surface of the three reference columns 52, and then as shown in FIG. 3B. By setting an axis passing through the center of the upper surface of the three reference columns 52, thereby determining the origin and the XYZ axes, and setting the orthogonal coordinates consisting of the origin and the XYZ axes, the spatial coordinates serving as the reference point coordinates can be obtained. Set.

例えば、２本の基準支柱５２の上面の中心を通る第１の軸線をＸ軸とし、残りの１本の基準支柱５２の上面の中心を通り、かつ、第１の軸線（Ｘ軸）に垂直な第２の軸線をＹ軸とし、第１の軸線（Ｘ軸）と第２の軸線（Ｙ軸）との交点（原点）を通り、かつ、第１の軸線（Ｘ軸）及び第２の軸線（Ｙ軸）に垂直な第３の軸線をＺ軸として、原点及びＸＹＺ軸を決めている。ここでは、座標基準面５３が、Ｚ＝０のときのＸＹ平面であり、基準点座標の基準面となる。そして、マスタＰＣ１２で作成したワーク表面形状データ及び加工制御用データは、この基準点座標に基づいて作成される。なお、第１の軸線、第２の軸線及び第３の軸線に対して、Ｘ軸、Ｙ軸及びＺ軸を互いに入れ換えて、ＸＹＺ軸を決めても良い。   For example, the first axis passing through the center of the upper surface of the two reference columns 52 is taken as the X axis, passing through the center of the upper surface of the remaining one reference column 52 and perpendicular to the first axis (X axis). The second axis is the Y axis, passes through the intersection (origin) of the first axis (X axis) and the second axis (Y axis), and the first axis (X axis) and the second axis The origin and the XYZ axes are determined with the third axis perpendicular to the axis (Y axis) as the Z axis. Here, the coordinate reference plane 53 is an XY plane when Z = 0, and is a reference plane for reference point coordinates. The workpiece surface shape data and machining control data created by the master PC 12 are created based on the reference point coordinates. Note that the XYZ axes may be determined by replacing the X axis, the Y axis, and the Z axis with respect to the first axis, the second axis, and the third axis.

（ステップＳ２）
作成したワーク表面形状データ及び加工制御用データをサーバＰＣ１４に予め保存しておく。なお、ワーク表面形状データ及び加工制御用データの作成は、サーバＰＣ１４で行っても良く、その場合、マスタＰＣ１２は省略可能である。 (Step S2)
The created workpiece surface shape data and machining control data are stored in the server PC 14 in advance. The creation of the workpiece surface shape data and the processing control data may be performed by the server PC 14, and in this case, the master PC 12 can be omitted.

（ステップＳ３）
３次元計測装置２０において、その３次元スキャナ２１を用いて、上記と同様の所定の位置及び姿勢で基準治具５０に設置したワークＷに対し、基準治具５０と共に３次元計測を行う。 (Step S3)
In the three-dimensional measuring apparatus 20, the three-dimensional measurement is performed together with the reference jig 50 on the workpiece W placed on the reference jig 50 at the same predetermined position and posture as described above, using the three-dimensional scanner 21.

（ステップＳ４）
３次元計測装置２０の計測ＰＣ２２を用い、基準治具５０に対する３次元計測から基準治具５０の基準支柱５２の上面の中心（３次元計測装置２０の座標系における座標）を認識し、認識した基準支柱５２の上面の中心に基づいて座標基準面５３を設定し、設定した座標基準面５３に基づいて３次元計測装置２０での基準点座標を規定する。３次元計測装置２０での基準点座標は、上記の図３（ｂ）で説明した基準点座標と同一である。 (Step S4)
Using the measurement PC 22 of the three-dimensional measurement apparatus 20, the center of the upper surface of the reference support 52 of the reference jig 50 (coordinates in the coordinate system of the three-dimensional measurement apparatus 20) is recognized and recognized from the three-dimensional measurement with respect to the reference jig 50. A coordinate reference plane 53 is set based on the center of the upper surface of the reference support column 52, and reference point coordinates in the three-dimensional measuring device 20 are defined based on the set coordinate reference plane 53. The reference point coordinates in the three-dimensional measuring apparatus 20 are the same as the reference point coordinates described with reference to FIG.

（ステップＳ５）
３次元計測装置２０の計測ＰＣ２２を用い、３次元計測によるワーク表面形状データを上述した基準点座標に座標変換する。つまり、３次元計測装置２０の座標系から基準点座標の座標系に座標変換する。 (Step S5)
Using the measurement PC 22 of the three-dimensional measuring apparatus 20, the workpiece surface shape data obtained by the three-dimensional measurement is coordinate-converted to the reference point coordinates described above. That is, the coordinate conversion is performed from the coordinate system of the three-dimensional measuring apparatus 20 to the coordinate system of the reference point coordinates.

（ステップＳ６）
座標変換後のワーク表面形状データとサーバＰＣ１４に保存してあるワーク表面形状データとの差（距離）をギャップデータとして求める。 (Step S6)
A difference (distance) between the workpiece surface shape data after coordinate conversion and the workpiece surface shape data stored in the server PC 14 is obtained as gap data.

上記ギャップデータについて、図４を参照して説明する。サーバＰＣ１４に保存してあるワーク表面形状データに基づくワークＷの表面Ｆ１と、３次元計測によるワーク表面形状データに基づくワークＷの表面Ｆ２は、同一の基準点座標で表されているので、図４に示すように、同一の基準点座標上に表すことができる。そして、同一の基準点座標上において、設計上のワークＷの表面Ｆ１と実測した実際のワークＷの表面Ｆ２の差（距離）をギャップＧとして計算することができる。   The gap data will be described with reference to FIG. Since the surface F1 of the workpiece W based on the workpiece surface shape data stored in the server PC 14 and the surface F2 of the workpiece W based on the workpiece surface shape data by three-dimensional measurement are represented by the same reference point coordinates, As shown in FIG. 4, they can be expressed on the same reference point coordinates. The difference (distance) between the designed surface F1 of the workpiece W and the actually measured surface F2 of the workpiece W can be calculated as the gap G on the same reference point coordinates.

本実施例では、レーザ加工機３０を用いて、ワークＷに穴開け加工を行うので、穴開け加工の品質及び精度を上げるには、焦点位置を表面に正しく合わせることが重要である。例えば、表面Ｆ１の任意の穴Ｐ１に着目すると、穴Ｐ１の中心位置（座標：Ｘ１、Ｙ１、Ｚ１）と穴Ｐ１の中心線Ｃの方向の位相のベクトル表示（ｉ、ｊ、ｋ）と座標変換後のワーク表面形状データを数値データとして解析ソフトに入力し、中心線Ｃが表面Ｆ２と交わる交点Ｐ２の交点位置（座標：Ｘ２、Ｙ２、Ｚ２）を求め、求めた交点Ｐ２の交点位置と穴Ｐ１の中心位置との差（距離）からギャップＧを計算することができる。このギャップＧが、設計上のワークＷと実際のワークＷとにおける穴開け加工の焦点距離の違いとなる。なお、ｉ、ｊ、ｋは、各軸のベクトル表示である。   In the present embodiment, the laser processing machine 30 is used to perform drilling on the workpiece W. Therefore, in order to improve the quality and accuracy of the drilling, it is important that the focal position is correctly aligned with the surface. For example, focusing on an arbitrary hole P1 on the surface F1, a vector display (i, j, k) and coordinates of the phase of the center position (coordinates: X1, Y1, Z1) of the hole P1 and the center line C of the hole P1. The converted workpiece surface shape data is input as numerical data to the analysis software, and the intersection position (coordinates: X2, Y2, Z2) where the center line C intersects the surface F2 is obtained, and the obtained intersection position of the intersection P2 and The gap G can be calculated from the difference (distance) from the center position of the hole P1. This gap G is a difference in the focal length of drilling between the designed workpiece W and the actual workpiece W. Note that i, j, and k are vector displays for each axis.

以上のような手順を、他に必要な加工位置で同様に行うことにより、上述したギャップデータを求めることになる。求めたギャップデータは、実際のワークＷの表面に焦点位置を正しく合わせるため、後述するレーザ加工機３０で用いられる。   The above-described gap data is obtained by performing the above procedure in the same manner at other necessary machining positions. The obtained gap data is used by a laser processing machine 30 described later in order to correctly adjust the focal position to the surface of the actual workpiece W.

（ステップＳ７）
レーザ加工機３０において、そのセンサ３６を用い、上記と同様の所定の位置及び姿勢で基準治具５０に設置したワークＷに対し、基準治具５０の基準支柱５２の上面の中心（レーザ加工機３０の座標系における座標）を位置認識する。 (Step S7)
In the laser processing machine 30, using the sensor 36, the center of the upper surface of the reference column 52 of the reference jig 50 (laser processing machine) with respect to the workpiece W placed on the reference jig 50 at the same predetermined position and posture as described above. (Coordinates in 30 coordinate systems) are recognized.

（ステップＳ８）
レーザ加工機３０の制御ユニット３３を用い、センサ３６で位置認識した基準支柱５２の上面の中心に基づいて座標基準面５３を設定し、設定した座標基準面５３に基づいてレーザ加工機３０での基準点座標を規定する。レーザ加工機３０での基準点座標も、上記の図３（ｂ）で説明した基準点座標と同一である。 (Step S8)
Using the control unit 33 of the laser processing machine 30, a coordinate reference plane 53 is set based on the center of the upper surface of the reference column 52 whose position is recognized by the sensor 36, and the laser processing machine 30 uses the set coordinate reference plane 53. Specify the reference point coordinates. The reference point coordinates in the laser processing machine 30 are also the same as the reference point coordinates described with reference to FIG.

（ステップＳ９）
レーザ加工機３０の制御ユニット３３を用い、サーバＰＣ１４に保存してある加工制御用データを上述したギャップデータで補正し、レーザ加工機３０で規定した基準点座標上において、補正後の加工制御用データを用いて、ワークＷを加工する工具となるレーザ発振器３４及び加工ヘッド３５を制御し、ワークＷの穴開け加工を行う。このとき、サーバＰＣ１４に保存してある加工制御用データを上述したギャップデータで補正しているので、実際のワークＷの表面に正しく焦点位置を合わせることができる。 (Step S9)
Using the control unit 33 of the laser processing machine 30, the processing control data stored in the server PC 14 is corrected with the above-described gap data, and the corrected processing control data is used on the reference point coordinates defined by the laser processing machine 30. Using the data, the laser oscillator 34 and the machining head 35 serving as a tool for machining the workpiece W are controlled, and the workpiece W is drilled. At this time, since the machining control data stored in the server PC 14 is corrected with the gap data described above, the focal position can be correctly aligned with the surface of the actual workpiece W.

以上説明したように、本実施例では、各装置で異なる座標系を、基準治具５０を用いることにより、同一の基準点座標に揃えており、この基準点座標に基づいて、ワークＷの表面形状の誤差補正を行って、ワークＷの穴開け加工を行うことができる。その結果、穴開け加工時の焦点位置を適切に合わせることができ、穴開け加工の品質及び精度を向上させることができる。   As described above, in this embodiment, different coordinate systems in each apparatus are aligned with the same reference point coordinates by using the reference jig 50, and the surface of the workpiece W is based on the reference point coordinates. It is possible to perform drilling of the workpiece W by correcting the shape error. As a result, the focal position at the time of drilling can be appropriately adjusted, and the quality and accuracy of the drilling can be improved.

本発明は、製造上の誤差があるワークに対して加工を行う場合に好適なものであり、例えば、成形誤差がある鋳物素材等のワークの加工に好適である。   The present invention is suitable for processing a workpiece having a manufacturing error, and is suitable for processing a workpiece such as a casting material having a forming error, for example.
