METHOD AND DEVICE FOR OPTIMIZING MACHINE TOOL CUTTING CONDITIONS

摘要

This device for optimizing machine tool cutting conditions optimizes the cutting conditions of a machine tool. It is possible to reduce machining time and cause the load to be uniform by means of being provided with: an NC program optimization function unit that on the basis of a tool pass and cutting conditions designed by CAM (12), makes changes such that the set value for the feed speed is slower at locations with a greater predicted cutting resistance and the set value for the feed speed is faster at locations with a smaller predicted cutting resistance, and on the basis of the load value and feed speed of an actual tool pass during a test machining performed on the basis of a tool pass and cutting conditions containing the set values for the feed speed that were subjected to the changes, by making changes again having subdivided the control cycle at locations for which it is determined that NC control cannot track the changes in machining shape, the cutting conditions are optimized; and a storage unit that stores the actual load values, feed speeds, and tool passes during the test machining.
