Numerical control machining center processing precautions

Common Issues in Part Processing with High-Speed Machining Centers:

1. When writing the production processing program, for processing positions with different dimensional tolerances in the high-speed machining center, the program should be written using the intermediate value of the specifications. The tool starting point should be selected at the datum point or standard.

2. Due to the parallelism requirements of the workpiece and the fact that the workpiece dimensions are mostly given in symmetrical specifications, when setting the tool in the high-speed machining center, the workpiece coordinate origin should be established at the center of the upper surface of the workpiece.

3. The selection of durable cutting tools should be based on various factors such as the raw material of the blank, alloy structural steel, and the characteristics of the high-speed machining center, depending on the processing conditions. At the same time, surface quality should also be considered.

4. When using a 90° countersink drill to process a C1 chamfer in the high-speed machining center, the depth of the cut should be calculated accurately to avoid over-processing the surface of the cross punch. Additionally, the actual radius of the processing position should be calculated and entered into the tool compensation table.

5. Before using the G28 command each time in the high-speed machining center, the G40 and G49 commands should be used to cancel the tool compensation, and the cutting tool should be returned to the reference point for tool changing. After changing to a new cutting tool, the G43 command should be used first to establish the length compensation for the new cutting tool.
