How to set the reference point of CNC machining CNC lathe and how to determine the coordinates?

You can see if the parameter setting of the reference point of your bed is correct.

Usually the CNC cutting system automatically processes the processed parts according to the pre-programmed processing program (commonly used drawing software AOTOCAD). We put the part's machining process route, process parameters, tool movement trajectory, displacement, cutting parameters (spindle revolutions, feed, back tooling, etc.) and auxiliary functions (tool change, spindle forward, reverse, etc.) Cutting fluid on, off, etc.), according to the instruction code and program format specified by the CNC cutting system, compile a processing program list, and then record the content of the program list on the control medium (such as punched paper tape, magnetic tape, disk, magnetic bubble Memory), and then input into the numerical control device of the numerical control machine tool, so as to direct the machine tool to process the parts.

This whole process from the analysis of the part drawing to the preparation of the control medium is called the compilation of the numerical control program. The difference between CNC cutting equipment and ordinary manual and semi-automatic cutting equipment when processing parts is that the CNC cutting equipment automatically processes parts according to the program, while ordinary manual and semi-automatic cutting equipment needs to be operated by humans. We only need to change the control of the machine tool. The program can achieve the purpose of processing different parts. Therefore, the CNC cutting equipment is especially suitable for processing small batches of parts with complex shapes and high precision requirements!

Since the CNC cutting equipment must process the parts according to the program, after the programmer has compiled the program, it is input into the CNC system to direct the work of the machine tool. The input of the program is through the control medium. In this way, using the numerical control system to control the finished parts can be modified by the drawing staff in time, and it is more free to use. The accuracy of the parts and components is also greatly improved compared with the accuracy of the semi-automatic cutting equipment!
