Exploration of NC Programming Experimental Teaching Based on Reverse Engineering

This paper puts forward the experimental course of the combination of reverse and numerical control programming. In the process of experiment teaching, the LK three coordinate measuring machine(CMM) is used to collect the data of the object, and NX Siemens software is used to realize the CAD inverse modeling, and then the Powermill numerical control programming software is used to carry on the numerical control programming. Through the opening of this experiment, Practice has proved that students not only master the advanced measurement technology, but also master the relevant technology of reverse design and NC programming. It has greatly improved the students' comprehensive application ability and innovation ability, also increased the students' employment competitiveness.
