In the shape, the highest point and the lowest point of the boss are measured, and the Z-DOWN and Z-UP items are respectively input. Select the CONTOURFINISH method and the system will calculate the machining path along the surface. Enter 015mm in the Downstep item, ie the cutting depth of each layer is 015mm. Because it is the finishing stage, the depth of cut of each layer of the tool directly affects the surface quality of the final mold, so it should be considered comprehensively under the factors of ensuring machining accuracy and efficiency. Note that the arc cutting is selected in the advance and retract mode, because in the finishing process, if the tool cuts into the workpiece straight, it will leave marks on the surface of the workpiece, so choose the appropriate cutting arc and also prevent the arc from being too large. Bumping other faces (in general, the system will automatically recognize and circumvent other cuts).
In the SRFOFFSET item, enter a margin value of 0mm (sometimes you can leave a lighting allowance according to the fitter's requirements). In finishing, generally select 001002mm in SRFTOL (surface accuracy). Finishing trajectory. Surface milling (SRFPKT) can be finished by layer cutting for steeper surfaces. For other forms of surface, SRFP-KT (surface milling) is used, and some software is called FIXCON-TOUR. Axis milling). The outer ring cavity surface is taken as an example. The bottom plane can be processed separately after the side surface is finished.
