What is NC programming?

Numerical control programming refers to the numerical control machining center, that is, the common machining machine tools are controlled by computers.

Numerical control machine tool is a mechanical and electrical integrated processing configuration with high technical integration and automation, and it is a product that comprehensively applies high-tech skills such as planning machine, active control, active detection and precision machine.

With the growth and popularization of CNC machine tools, the demand for skilled talents who know both CNC machining skills and CNC machining programming will continue to grow. CNC lathe is one of the most widely used CNC machine tools. In this paper, the step style in NC lathe parts processing is discussed.

Programming steps:

After getting the part drawing, we should finally analyze the part drawing and determine the processing technology, that is, determine the processing essentials (such as fixture and positioning essentials) and processing paths (such as feed path, tool setting point and tool changing point). ) and process parameters (such as feed speed, spindle speed, cutting speed and cutting depth, etc. ) part.

Secondly, numerical planning should be carried out. As far as possible, most local CNC systems have the tool compensation function. Only by planning the coordinate values of the adjacent intersections (or tangents) of several elements, the coordinate values of the starting point and the center of the arc can be obtained.

Finally, according to the coordinate values of the planned tool path, the determined machining parameters and help actions, combined with the coordinate instruction code and step mode used by cnc system rules, the part machining step list is written step by step and input into the memory of CNC device.
