With the development of numerical control technology, the machining accuracy of parts is required to be higher and higher. In actual processing and production, CNC machine tools can not give full play to its performance, and there are still many shortcomings in processing high-precision workpieces. In order to meet people's requirements for the machining accuracy of workpieces, we need to find out the factors that affect the machining accuracy of CNC lathes, and formulate corresponding CNC tool optimization schemes for these factors.

With the development of science and technology, machinery more and more frequently appear in people's lives, numerical control technology is applied to all areas of people's lives. Compared with ordinary lathes, CNC lathes have obvious advantages in processing accuracy, operating efficiency, and degree of automation. With the development of numerical control technology, the machining accuracy of parts is required to be higher and higher. In actual processing and production, CNC machine tools can not give full play to its performance, and there are still many shortcomings in processing high-precision workpieces. In order to meet people's requirements for the machining accuracy of workpieces, we need to find out the factors that affect the machining accuracy of CNC lathes, and formulate correspondingNC Tool Optimization Scheme.

1. The working principle of CNC lathe

The numerical control system (computer numerical control system) is added to the machine tool body of the ordinary lathe, forming a new type of lathe that integrates a number of advanced science and technology. It has the advantages of high processing accuracy, high operating efficiency and high degree of automation. At present, it has been widely used in mechanical processing industry. The working principle of CNC lathes is different from that of traditional lathes. It describes and organizes the language of the actual parts to be processed by the numerical control equipment, transmits it to the computer control system, and then operates. This process is completed through digital transmission equipment, numerical control devices, control panels, etc. The working process is: the staff first installs the parts to be processed on the fixture of the machine tool body; the processing requirements of the parts to be processed by the staff (Processing shape, size and accuracy, etc.) are input into the numerical control system through the control panel; the staff draws the information (tool path and other related information) of the parts that need to be processed in the numerical control system; the above information is converted into code by the numerical control equipment and recorded in the program, and then transmitted to the numerical control system [2]; the PLC system transmits to The information of the control system is decoded and calculated, and then the instructions are sent to the circuit, the spindle servo device and other auxiliary devices; all the equipment in the numerical control system will drive the machine tool (according to the data input and conversion before), in order to process the parts that meet the requirements.

　　2、NC Tool Optimization SchemeThe characteristics of CNC lathe

Compared with traditional machine tools, CNC lathes have added CNC systems, which have obvious advantages in all aspects of work. Mainly reflected in four aspects:

① High machining accuracy. CNC lathe increases the CNC control system on the basis of the traditional lathe. The accuracy of the system is very high, which can provide stability and consistency guarantee for the processing of mechanical parts.

② High processing depth. The CNC control system can realize the function of multi-coordinate linkage by compiling various programs, so it can process mechanical parts with more complex shapes.

③ Improve work efficiency. The system can control different machining parts by changing the input program. The system can save the calculation and evaluation time of parts, so as to improve the work efficiency.

The high degree of automation. The efficiency of CNC lathe processing parts is several times that of traditional lathe. The degree of automation is high, and parts can be processed in batches, which improves work efficiency and reduces the work intensity of employees.
