Below in conjunction with example in detail the present invention.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
Fig. 2 is the structure and the parameter synoptic diagram thereof of virtual " composite part ".
Embodiment
Referring to Fig. 2: at first technology person can finish numerically controlled lathe the axial workpiece of processing, carry out signature analysis, the machining feature of comprehensive all parts according to group technology principle virtual one " composite part ", should " composite part " have all characteristic segments that axial workpiece may occur.The parameter-definition of each characteristic segments such as following table:
| Characteristic segments | Diameter | Pitch | Length | Arc radius | The chamfering parameter | |
| Length | Angle | |||||
| Screw thread | G | T | L | |||
| Grooving | φ | Δ | ||||
| Cylinder | φ | L | ||||
| Preceding recessed round platform | φ 1、φ 2 | L | Ra | |||
| The lordosis round platform | φ 3、φ 4 | L | Rb | |||
| The recurve round platform | φ 4、φ 5 | L | Rc | |||
| Back dome platform | φ 6、φ 7 | L | Rd | |||
| Preceding chamfering | F | θ | ||||
| Back chamfering | E | θ | ||||
Work out the processing technology of virtual " composite part ", write nc program according to processing technology, deposit among the ROM of lathe control computer, this program has the program segment of each characteristic segments correspondence.
Referring to Fig. 1, specific process is as follows:
Behind the computer booting, the operator presses the order of connection of each characteristic segments of work piece, imports the characteristic parameter of each section piecemeal, after computing machine reads, select characteristic of correspondence section in the model that prestores, and calculate, revise each characteristic segments piecemeal, form the model of work piece according to the value of input parameter.
For example: first section of work piece is thread segment, then import its parameter external diameter G, pitch T, length L and value thereof, after computing machine reads, characteristic of correspondence section in the model of selecting to prestore, and calculate, revise this characteristic segments according to the value of parameter, form the model of this characteristic segments.If second section is cylindrical section, then import its characteristic parameter diameter phi, length L and value thereof, after computing machine reads, as calculated, revise to form the model of this characteristic segments.If the 3rd section is back chamfering section, then import chamfering characteristic parameter length E, angle θ, if the 4th section is grooving, then import its characteristic parameter diameter phi, length Δ and value thereof; If the 5th section is preceding recessed round platform section, then import its characteristic parameter diameter phi
1, φ
2, length L, arc radius Ra and value thereof ..., the rest may be inferred, imports the parameter value of work piece in regular turn piecemeal, forms the block mold of work piece at last.
Computing machine calculates the cutter path parameter value of work piece according to the value of characteristic parameter of input, i.e. the coordinate figure of X, Z axle generates the cutter path of work piece automatically.
Then, simulation shows process on the CRT of lathe control device display screen, whether the operator observes cutter path and matches with the figure of work piece, if certain characteristic segments misfits, the operator can be by the keyboard on the guidance panel of numerically-controlled machine, revise X, Z axial coordinate value in the corresponding program segment of this characteristic segments, match up to the figure of cutter path and part to be processed.
So far, the operator can carry out cut according to amended cutter path.
