In the field of CNC processing industry, CNC processing is also known as CNC machine tools. It mainly refers to the path of feed processing. It refers to the path through which the turning tool starts to move from the tool setting point (or the fixed origin of the machine tool) until it comes back to this point and completes the processing program, including the path of cutting processing and the path of non cutting empty stroke such as cutting in and cutting out of the tool. These are NC commands to complete the operation automatically.
In the process of finishing, the feeding path is basically carried out along the order of parts generalization. Therefore, the key point of determining the feeding path is to determine the feeding path of rough machining and empty stroke.
In the process of NC machine tool machining, the machining process should follow the following rules.
- It should be able to ensure the accuracy and surface roughness of the workpiece to be processed.
- Make the processing path shortest, reduce the empty travel time and improve the processing power.
- Simplify the amount of numerical calculation and the processing procedure as much as possible.
- Subprogram should be used to save processing time for some repeated programs.
