Generally, the workpiece processed by computer gongs has complex shape, many working procedures 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 more complex. Consider the following when programming.
1. Carefully analyze the drawings and determine the reasonable process route.
2. The size and specification of the tool shall be selected, and the measured actual size shall be filled into the tool card.
3. Determine reasonable cutting parameters. It mainly includes spindle speed, back draft, feed speed, etc.
4. 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 machine origin.
5. In order to facilitate the inspection and debugging of the program, the processing contents of each step can be arranged in different subprograms, while the main program mainly completes the tool change and subroutine call. This procedure is simple and clear.
6. Check and test run the programmed program, and pay attention to whether there is interference between tools, clamps or workpieces. When checking the m, s and t functions, it can be carried out under the z-axis locking state.
