A programming method with the optimal block length for high-speed high-precision 5-axis machining(4th report)

Effects of acceleration/deceleration delay, tool center point (TCP) position and speed differences between blocks

Abstract

In the previous report, we identified the block processing time (Tb) and reported the successful implementation of high-speed and high-precision simultaneous 5-axis machining by creating a CNC program with the optimal block length based on the identified block processing time. In this study, we report that this optimal block length programming method can achieve high-speed, high-precision machining by being less susceptible to increases and decreases of acceleration/deceleration delay, tool center point (TCP) position, and speed differences between blocks than conventional programming methods.
