Title: Numerically controlled grinding machine
Inventor: YONEDA TAKAO
IPC: B24B47/20
Filed: 1992-11-26
Abstract: PURPOSE:To stabilize the grinding work precision by varying the feeding speed of a grinding wheel based on the oscillation quantity which is calculated in real time during grinding. CONSTITUTION:In the step 130, it is judged if the variation quantity (d) calculated in the step 128 exceeds the allowable oscillation value (alpha) or not. At this time, if the inequal equation d>alpha' is established, transfer to the step 132 is performed, and it is judged if oscillation exists or not. When the existence of oscillation is judged, transfer to the step 134 is performed, and the new instruction speed VQ (VQ<VP) is calculated in substitution for the instruction speed VP at present, and the speed change processing to the instruction speed VQ is executed. In this case, VQ is represented by f(VP, d, DELTAd). However, DELTAd is the variation quantity representing the difference between the variation quantity (d) based on the measurement value at this time and the value in the preceding time.
