本発明は、研削加工装置に関し、特に切込送り速度を途

除去するための切込控え後退を行なうようにした研削加
工装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grinding device, and in particular, the cutting feed rate is changed midway through the cutting process, and the cutting speed is changed to remove the deflection of the grinding wheel at the time of the switching. This invention relates to a grinding device that performs back-and-forth movement.
一般に、研削加工はワークの被加工部の寸法を測定しな
がら砥石を回転及び往復動させ、かつワークを砥石に対
して相対的に切込ませることによって行なわれている。In general, grinding is performed by rotating and reciprocating a grindstone while measuring the dimensions of a portion of the workpiece to be machined, and cutting the workpiece relative to the grindstone.
そして、この研削加工においては、加工精度を確保し、

石軸のたわみの復元力のみでの研削（スパークアウト）
を行なうようにしている。In this grinding process, we ensure machining accuracy,
In addition, from the perspective of improving machining efficiency, the cutting feed rate of the workpiece relative to the grinding wheel is changed to several levels when the workpiece reaches a preset machining dimension.For example, the cutting feed rate is changed to three levels. Grinding is performed at the maximum cutting feed rate until the machining dimension of the workpiece reaches the first set dimension, then grinding is performed at a slower speed than the previous step until the workpiece reaches the second set dimension, and finally the cutting speed is increased. Grinding using only the restoring force of the grinding wheel shaft deflection without increasing the feed rate (spark out)
I try to do this.

ークが第１の設定寸法になった時点で、一旦ワークを砥
石に対して相対的に後退させて上記たわみを除去する、
いわゆる切込控え後退を行なうようにしている。By the way, in grinding, the workpiece is pressed relative to the grindstone, so the grindstone shaft that supports the grindstone is deflected in the direction perpendicular to the axis, that is, in the cutting feed direction, and this deflection affects the machining accuracy. This will have a negative impact on Therefore, conventionally, when switching the cutting feed rate, that is, when the workpiece reaches the first set size, the workpiece is temporarily retreated relative to the grindstone to remove the deflection.
A so-called cut-back retreat is performed.
このような切込控え後退を行なうようにした研削加工装

過ぎると、今度は上記送り速度の切換後に一定時間研削

。Conventionally, there are grinding machines that perform this kind of cut-back and retreat while performing grinding while intermittently measuring the machining dimensions of the workpiece. There are cases where the first set dimension is reached during non-measurement, and the first set dimension is exceeded during the next measurement, and in such a case, the amount of cut-back reserve will be insufficient by the amount of the above-mentioned excess. Become. If the amount of cutting retreat is too small, a problem arises in that deflection remains after switching the feed rate, leading to a decrease in machining accuracy. In order to prevent this problem from occurring, it is possible to set this retraction amount to a large value, but if it is set too large, a state will occur in which grinding is not performed for a certain period of time after switching the feed rate, which will reduce machining efficiency. will decrease.
そこで本願出願人は、上記切換時点でのオーバー量を検

昭５８−１０９９５５号参照）。Therefore, the applicant of the present application has filed an application for a grinding device that detects the amount of overflow at the time of switching and increases the amount of cut-off retreat in accordance with this detected value (Japanese Patent Application No. 109955/1983). (see issue).
［発明の目的〕

え後退量を大きくするようにしたものである。By the way, as mentioned above, the amount of cut-back retreat is determined according to the amount of deflection of the grinding wheel shaft, but the present inventor believes that the amount of deflection of the grinding wheel shaft changes depending on various factors, It was discovered that the deflection amount increases as the sharpness of the grinding wheel worsens. Therefore, the present invention provides a grinding device that includes a cutting feed device, a means for detecting the sharpness of the grindstone, and a means for detecting the sharpness of the grindstone. Accordingly, a control device is provided to control the cutting feed device, so that the worse the cutting quality, the larger the amount of cutting advance retreat.

工は上記の場合と同様に行なわれる。Next, to explain the case where the number of workpieces to be ground becomes nl, the number of workpieces n1 is
A retreat amount s1 corresponding to the amount is output. In this case, the sharpness of the grinding wheel 4 has deteriorated, and the grinding wheel shaft 3 is pressed so hard that it becomes easily bent, and as a result, the above-mentioned grinding amount cannot be obtained until the cutting has been made more than in the above case. is ground according to curve 11. Then, when the inner diameter DQ of the workpiece W matches Dl, the cut-preparation retreat operation is performed with the above-mentioned retreat amount s1, and as a result, the grinding wheel 4
will retreat to the same position as above. Note that the subsequent processing is performed in the same manner as in the above case.
このように本実施例では、研削ワーク数ｎが多くなるほ

たわみを完全に除去でき、精度の高い研削面を得ること
ができ、加工能率を向上できる。As described above, in this embodiment, as the number n of workpieces to be ground increases, that is, as the sharpness of the grinding wheel 4 deteriorates and the amount of deflection of the grinding wheel shaft 3 increases, the amount of cutting retreat is increased to obtain the optimum cutting depth. Since the grinding wheel shaft 3 is moved back to the position, even if the amount of deflection of the grinding wheel shaft 3 increases, the deflection of the grinding wheel shaft 3 can be completely removed at the time of switching the cutting feed rate, and a highly accurate ground surface can be obtained. Machining efficiency can be improved.
なお、上記実施例では、研削ワーク数が増加すると切味
が低下する通常の砥石を用いた場合について説明したが
、このように加工数量に比例して切味が悪くなる通常の
砥石とは逆に、例えばボブラン砥石のよらに加工数量が
増加するにつれて切味が向上するものもあり、ボブラン
砥石がこのような逆の傾向になるのは、砥粒自体が硬い
とともに、結合材も強いものが使用されるからであり、
そのためドレス直後は砥石面が平面状となり研削能力は
低下するが、加工して行くに伴なって砥粒が表面に現わ
れてきて研削能力が向上するからであると考えられる。In addition, in the above example, a case was explained in which a normal whetstone is used, in which the cutting quality deteriorates as the number of workpieces to be ground increases.However, this is the opposite of a normal grindstone, in which the cutting quality deteriorates in proportion to the number of workpieces processed. For example, there are some types of whetstones, such as Bobrun whetstones, whose sharpness improves as the amount of processing increases.The reason why Bobrun whetstones show the opposite tendency is that the abrasive grains themselves are hard and the binding material is strong. This is because it is used;
This is thought to be because immediately after dressing, the grinding wheel surface becomes flat and the grinding ability decreases, but as the grinding progresses, abrasive grains appear on the surface and the grinding ability improves.
そして上記ボブラン砥石の場合は第４図とは逆に加工数
量が増えると切込控え後退量Ｓは減少することとなる。In the case of the Bobrun grindstone, contrary to FIG. 4, as the number of machining increases, the cutting reserve retreat amount S decreases.
また上記実施例では、砥石４の切味のパラメータとして
、ドレッシング後の研削ワーク数を使用したが、このパ
ラメータは研削ワーク数に限定されるものではなく、例
えば砥石の径等があり、この場合大径の砥石の方が小径
のものより研削電力が大きくなり、切味は悪いという傾
向がある（第５図参照）。このような傾向になるのは、
径が小さくなるとワークにくい込み易くなるとともにク
ーラント液もかかりやすいためと考えられる。Furthermore, in the above embodiment, the number of grinding works after dressing was used as a parameter for the sharpness of the grinding wheel 4, but this parameter is not limited to the number of grinding works, and includes, for example, the diameter of the grinding wheel. A grindstone with a large diameter tends to require more grinding power than one with a small diameter, resulting in poorer cutting quality (see Figure 5). This tendency is due to
This is thought to be because the smaller the diameter, the easier it is to sink into the workpiece, and the easier it is for coolant to splash onto it.
以上のように、本発明に係る研削加工装置によれば、砥
石の切味が悪いほど切込控え後退量を大きくしたので、
砥石軸のたわみ量が増大してもこれを確実に除去でき、
加工精度及び加工能率を大きく向上できる効果がある。As described above, according to the grinding device according to the present invention, the cutting depth is increased as the sharpness of the grindstone deteriorates.
Even if the amount of deflection of the grinding wheel shaft increases, this can be reliably removed.
This has the effect of greatly improving machining accuracy and machining efficiency.
