1. When programming the high speed machining centre cnc, the machining parts with asymmetric tolerances should be programmed with the median size, and the starting point should be selected on the datum plane or datum point.
2. Since the workpiece has a symmetry requirement, and the size of the workpiece is mostly given in a symmetrical size, the origin of the workpiece coordinate is set at the center of the upper surface of the workpiece during tool setting.
3. The selection of cutting amount of high-speed CNC machining center should be based on various factors such as blank material, tool material, machine tool performance, etc. according to the processing conditions, while taking into account the surface quality.
4. When using 90° countersinking to process C1 chamfers, the depth of the feed must be calculated to avoid over-processing the surface of the cross boss, and the actual radius of the processed part must be calculated and filled in the tool compensation table.
5. Before each use of G28, use G40 and G49 to cancel tool compensation and return the tool to the reference point for tool change. After the high-speed machining center is replaced with a new tool, the G43 command must first be used to establish the length compensation of the new tool.
