Abstract
A machining apparatus, in which a plurality of user set programs in relation to one axis is written and the amount of the infeed motion of the grinding wheel is increased to restrain the change of the load of the grinding wheel, improves a machining accuracy and achieve a longer life of the grinding wheel. When the grinding wheelcut arc portionsA,C, U having its diameter of which is gradually small according to a position apart from the shoulder, the numerical controllercontrols a rotation of the workpiecearound said C-axis, a motion of a grinding wheelrelative to the workpiecealong an X-axis and Z-axis to trace an arc profile of the arc portionA,C, U of the extending portion, and an infeed motion of the grinding wheelto the workpiecealong the X-axis to increase gradually an amount of the infeed motion of the grinding wheelto the workpiecealong the X-axis in order to grind the extending portion to the arc profile and in order to increase gradually a grinding load of the grinding wheel
