The operation principle of precision hardware processing control system precision hardware machining operation principle CNC computer lathe machining control system can control machine tools to automatically start and stop, change direction and speed change according to digital program instructions. It can automatically control feed speed, direction and machining route, process, select cutting tools and base on Tool size adjustment, tool feeding and walking path can complete various auxiliary actions needed in machining. When NC machine tools are used to process parts, the graphics and process parameters, processing steps, etc. are only needed in the form of digital information, which are programmed into the control system of the machine tool, then the operation is processed to drive the instruction signal of the servo mechanism, thus controlling the coordinated action of the parts of the machine tool and automatically adding the parts. Work out the parts. When the processing object is replaced, only the program code is rewritten and input to the machine tool, the NC device can replace most of the functions of the human brain and hands, and the whole process of processing can be controlled and any complex parts can be produced.

When we use machine tools to process parts, CNC computer lathe processing usually needs to control the various movements of the machine tool, one is to control the sequence of action, and the two is to control the displacement of the moving parts of the machine tool. CNC computer lathe processing by ordinary machine tool processing, this kind of driving, parking, knife, reversing, spindle speed change and switch cutting fluid are controlled manually. The machining operations and motion parameters of the CNC computer lathe are controlled in the form of analog quantities, such as the designed cam, the die and the block, which can process more complex parts with a certain flexibility and generality, but the machining accuracy of the parts is affected by the machining accuracy of the parts. The influence of cam and profiling on manufacturing accuracy is also very long.
