A programming method with the optimal block length for high-speed high-precision 5-axis machining (3rd report)

Identification of the block processing time (Tb)

Abstract

In the previous report, we reported that a CNC program with tool center point control generated by block length based on the CNC’s block processing time (Tb) described in the manual enables simultaneous 5-axis machining with higher-speed and higher-precision. In this paper, the block processing time (Tb) is identified by test operation using a more general method than previous studies. It is reported that a CNC program is generated based on the identified block processing time (Tb) and simultaneous 5-axis machining can be performed with higher-speed and higher-precision by machining a workpiece using the generated program.
