The Development of Special CNC System for Profiling Lathe Based on Digital Capture Measurement

Abstract

Aimed at the goal of digital capture function for CNC profiling lathe, it has conducted researches on the key technologies of CNC system development, including automatic profiling measurement, profiling data collection methods and G-code program automatically generation. Before process, use an on-off-type laser sensor along the planned path close to the sample workpiece point by point to get series of coordinate points of the contour through the CNC system position latch function and the switch of senors state; through subsequent processing methods: contour segmentation, curve filtering, etc. And generate the G-code program for process. Practice shows that this special CNC system for profiling lathe, not only integrates automatic profiling data acquisition, automatic generation of process G code program, and has the characteristics of simple structure, easy operation and high efficiency.
