Generally, the workpiece processed by computer gong has complex shape, many processes, and many kinds of cutting tools. It is often necessary to complete the whole process from rough machining, semi finish machining to finish machining after one clamping. So the program is complicated. The following problems should be considered when programming.
- Carefully analyze the drawings and determine the reasonable process route.
- The size of the tool should be selected, and the measured actual size should be filled in the tool card.
- Determine the reasonable cutting parameters. It mainly includes spindle speed, back feed, feed speed, etc.
- There should be enough space for automatic tool change to avoid collision with workpiece or fixture. It is recommended to set the tool change position at the origin of the machine tool.
- In order to check and debug the program, the processing contents of each step can be arranged in different subprograms, and the main program mainly completes tool change and subroutine call. This procedure is simple and clear.
- Check and trial run the programmed program, and pay attention to whether there is interference among tools, fixtures or workpieces. When checking m, s and t functions, it can be carried out in the z-axis locking state.
