Anonymous users2024-02-07CNC machine tools are automatically processed on the processed parts according to the pre-programmed processing program. We will part the processing process route, process parameters, tool trajectory, displacement, cutting parameters (spindle revolution, feed, back eating tool, etc.) and auxiliary functions (tool change, spindle rotation, reversal, cutting fluid on, off, etc.), in accordance with the instructions and program format specified by the CNC machine tool into a processing program sheet, and then record the content of the program sheet on the control medium (such as perforated paper tape, tape, disk, magnetic bubble memory), and then input into the CNC machine tool CNC device. Thus directing the machine tool to process parts.
This whole process from the analysis of the part diagram to the production of the control medium is called the preparation of numerical control programming. The difference between CNC machine tools and ordinary machine tool processing parts is that the control machine tool is to automatically process parts according to the program, while the ordinary machine tool is operated by people, and we only need to change the program to control the action of the machine tool to achieve the purpose of processing different parts. Therefore, CNC machine tools are particularly suitable for processing small batches of parts with complex shapes that require high precision.

Anonymous users2024-02-01CNC lathe programming** is G00 quick positioning instruction, G01 linear interpolation instruction, etc. The G00 quick positioning instruction format is G00XUZW, XZ is the target point when absolute programming, UW is the target point when relative programming, and the two axes start to move at the fastest speed of the machine tool at the same time, but not necessarily stop at the same time, that is, the synthetic tool path is not necessarily a straight line.
Features of CNC lathe programming**G28 return reference point instruction, the format is G28XUZWT0000, if the machine tool is started back to the zero point, then the execution of this instruction makes the tool holder return to zero through the specified point, otherwise move to the position when the system is powered on through the specified point, G02 circular interpolation instruction, the format is G02XUZWRIK, FXZ is the target point when absolute programming, UW is the target point when relative programming.
G27 return reference point detection instruction, the format is G27XUZWT0000, this instruction must be executed before the tool holder back to zero once, if the specified two coordinate values are the coordinate values of the reference point of the machine tool, and the two zero reference point indicators on the machine tool panel are on, it means that the zero point of the machine tool is correct, otherwise the positioning error of the machine tool is too large.
The format of the interpolation instruction G03 with an arc is as follows: >>>More

CNC machine tools were born to adapt to the mass automated production of modern industrial production, and the key word is automation. The flat bed CNC lathe is transformed from the ordinary lathe with simple numerical control, and the consideration of automation is not comprehensive. The inclined bed CNC lathe is developed and designed according to the principle of CNC machining, and the pertinence is very strong, in terms of the layout, rigidity, accuracy, and chip removal capacity of the machine tool, it has been significantly improved compared with the flat bed CNC lathe. >>>More
