摘要：
This paper presents a new machining technology of die/mold to keep constant cutting force by controlling both the feed rate and the spindle speed depending on the machining profile. First, we measure the control capacity of spindle speed on up-to-date machining centers and confirm that they have the acceleration rate up to 100/s2. Under the control of feedrate and spindle speed, cutting tests of hardened steel with sinusoidal shapes are conducted by using a square end mill. Experimental results show that newly developed method is very effective for cutting die/mold in high accuracy and high productivity.
