How to set the reference point and coordinate of NC lathe in NC machining?

You can see if your bed reference point parameters are set correctly.

Generally, CNC cutting system automatically processes the parts to be processed according to the pre programmed processing program (commonly used drawing software aotocad). According to the instruction code and program format specified by the NC cutting system, a machining program sheet is compiled for the machining process route, process parameters, tool movement path, displacement, cutting parameters (spindle rotation, feed rate, back feed, etc.) and auxiliary functions (tool change, spindle forward rotation, reverse rotation, cutting fluid on and off, etc.), and then record the contents of this program list in the NC cutting system Control medium (such as perforated paper tape, magnetic tape, magnetic 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 parts.

The whole process from analysis of part drawing to making control medium is called NC programming. The difference between CNC cutting equipment and ordinary hand and semi-automatic cutting equipment in processing parts is that CNC cutting equipment automatically processes parts according to the program, while ordinary hand and semi-automatic cutting equipment needs to be operated by people. We can achieve the purpose of processing different parts as long as we change the program that controls the action of the machine tool. Therefore, CNC cutting equipment is particularly suitable for processing small batch and complex shape parts with high precision requirements!

Because the CNC cutting equipment must process parts according to the program, the programmer will input the program into the CNC system to direct the work of the machine tool. The program input is through the control medium. In this way, the NC system is used to control and complete the processing of parts. The drawing staff can modify the graphics in time, and the accuracy of the parts is greatly improved compared with that of the semi-automatic cutting equipment!
