The main problem of the ring cutting is that it needs enough Convolute space, sometimes the graphics are complicated, and the convolute coverage may not be complete. The spiral method also avoids the shifting and commutation between the rings. The ring cutting can keep the milling method unchanged. The ring cutting method is to process from the inside to the outside or from the outside to the inside according to the shape. After that, the tool lifts back quickly and then starts a new round, you can always maintain the down milling or up-cut milling mode. Two-way cutting generates a set of spaced reciprocating linear tool paths to cut grooves the tool path generated by one-way cutting is similar to that of two-way cutting, except that one-way cutting completes a straight line. Line cutting includes two-way cutting and one-way cutting. Mastercam 9.0 provides 8 kinds of rough cutting methods: Zigzag (two-way cutting) Constant Overlap Spiral (equal distance circular cutting), Parallel Spirall (surround cutting), Parallel Clean Cornres (circular cutting and clear angle) Morph Spiral (according to the shape) The 8 cutting methods of Circumferential Cutting, High Speed, One Way, and True Spiral can be further divided into two categories: line cutting and circumferential cutting. In grooving processing, the machining allowance is generally relatively large, and the processing efficiency can be improved by setting the rough and finishing parameters.
