After the machining process is determined, the CNC machining equipment needs to be programmed to process the workpiece, so what matters should engineers pay attention to when programming machining?

1. Need to understand the workpiece clamping method;

2. It is necessary to know the size of the workpiece blank in order to determine the scope of machining and whether multiple clamping is required;

3. It is necessary to understand the material of the workpiece in order to select the tool selection during processing;

4. It is necessary to understand the tools in stock, so as to avoid program modification due to the lack of such tools during processing. If such tools must be used, they should be prepared in advance;

5. The setting principle of the safety height in programming is to be higher than the highest surface of the island, or to set the programming zero point on the highest surface, so as to avoid the risk of knife collision as much as possible;

The above points need to be paid attention to when carrying out machining CNC programming, so that a program suitable for workpiece machining can be written more accurately and efficiently.
