Various cutting methods of CNC machining center

1. Reciprocating cutting

Reciprocating cutting method creates reciprocating parallel cutting tool paths, keeps continuous motion during the step motion, and can remove the material to the maximum without lifting the tool, which is the most economical and convenient cutting motion. This cutting method coexists with forward milling and reverse milling. If wall cleaning is enabled, it will affect the tool path direction of wall cleaning, so as to maintain the wall cleaning as pure forward milling or reverse milling.

2. Unidirectional cutting

One-way cutting method produces parallel and one-way cutting tool path, and the return journey is a fast crossing movement, because there is no cutting during the return journey, it will affect the machining efficiency. One-way cutting can always maintain consistent forward milling or reverse milling cutting, and is usually used for surface machining of islands and occasions where reciprocating cutting methods are not applicable, such as some ribs with steep walls, which are generally used for surface finishing.

3. One-way cutting along the contour

One-way cutting along the contour is used to create parallel, one-way tool paths along the contour, and always maintain forward milling or reverse milling cutting. The wall quality of machining is better than that of reciprocating cutting and unidirectional cutting, and the cutting is relatively smooth and has no impact on the tool, so it is usually used to process parts with high requirements on side walls or thin-walled parts.

4. Follow the peripheral cutting

The method of following the periphery is mainly used to create sequential and concentric tool paths along the contour, which is obtained by offsetting the periphery contour, and all the paths are presented in a closed form in the machining area. The tool path that follows the peripheral cutting is a continuous cutting tool path, which has no blank cutting, and can basically maintain simple forward milling or reverse milling, so it can not only maintain high cutting efficiency, but also maintain cutting stability and ensure machining quality. It is usually used for rough machining of parts with islands and cavities.

5. Follow the workpiece cutting

Following the workpiece cutting method, a series of tool paths with all specified contours of the machined parts are generated, which are not only the peripheral wall of the cutting area but also the islands in the cutting area. These tool path shapes are obtained by offsetting the outer contour and the island contour of the cutting area. The tool path that follows the workpiece cutting is a continuous cutting tool path.

Without blank cutting, it can maintain simple forward milling or reverse milling, so it can not only maintain high cutting efficiency, but also maintain cutting stability and ensure machining quality. It is usually used in cavity machining areas with islands.

6. Cycloidal cutting

Cycloidal cutting method is used to produce small circles around the contour, so as to avoid the large amount of cutting material caused by full-cutter cutting. Cycloidal cutting is suitable for high-speed machining, and it is processed with relatively uniform cutting load.
