- CNC Advanced Programming Lecture Notes doc version
- In CNC machining, line cutting and ring cutting are two typical tool paths. Line cutting is mostly used for regular rectangular planes, step surfaces and rectangular sunken processing during manual programming. Line cutting in non-rectangular areas is generally implemented using automatic programming. Circular cutting is mainly used for semi-finishing, finishing and roughing of contours. When used for roughing, its efficiency is lower than that of line cutting, but it can be easily realized with the tool compensation function. This book is comprehensive in content, rich in examples, and comprehensive in system. This platform provides download of the doc version of advanced CNC programming lecture notes. Friends who need it can download it and take a look!
