In the CNC metal processing process, special attention should be paid to the determination of the tool point and change point of the CNC metal processing center. This is the starting point of the tool relative to the workpiece in CNC machining. Because from this point, the machining program is executed, and the tool point is also called the starting point or starting point of the program. When programming, you should first consider the selection of the tool point position.
When the machining accuracy is not high, some surfaces on the workpiece or fixture can be used as the surface of the tool. When the machining accuracy is high, the tool point should be selected on the design reference or process reference of the part as much as possible. For parts with hole positioning, it is best to use the axis of the hole as the tool point.
On the other hand, in the CNC machining process, the tool point must have a certain coordinate relationship with the positioning datum of the workpiece to determine the relationship between the machine tool standard system and the workpiece coordinate system. The selection of tool points should facilitate the calculation of coordinate values and facilitate tool position alignment. When adjusting the tool position, the centering point should coincide with the tool position.
In the process of CNC machining of hardware parts, we must give full play to the subjective initiative of people. From process design, program design to the implementation of the processing process, it is necessary to strengthen details, strengthen control and control, and minimize unnecessary losses and operating errors caused by process design.
The above is all the details that cannot be ignored in CNC hardware processing summarized by Hongfa Shunda, I hope it will be helpful to everyone!
