When programming, we should first consider the selection of 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 far as possible. For example, for the part with hole positioning, it is best to take the axis of the hole as the tool point.
On the other hand, in the process of NC machining, the tool point must have a certain coordinate relationship with the positioning datum of the workpiece in order to determine the relationship between the machine tool standard system and the workpiece coordinate system. The selection of tool points shall facilitate the calculation of coordinate values and the alignment of tool positions. When adjusting the tool position, the centering point should coincide with the tool position.
In the process of NC machining of hardware parts, we must give full play to people's subjective initiative. From the process design, program design to the implementation of the processing process, we must strengthen the details, strengthen the control and control, and minimize the unnecessary loss and operation error caused by the process design.
