Technical Analysis of Control Accuracy in Precision Hardware Processing

In the process of precision metal processing, it is very important for the operator of CNC processing to control the precision of precision metal processing. In order to improve the precision of precision metal processing, it is necessary to improve. From the analysis of hardware, software and machining process, we propose measures to improve machining. Below we will specifically describe the technology of precision metal processing to improve accuracy.

1) Real-time monitoring system for precision hardware processing

In order to be able to find out in time the problem of precision hardware processing accuracy decline during processing, a virtual simulation system should be established to monitor the processing situation in real time and provide further guidance based on system feedback. At the same time, the machining machine tool should study a more controllable precision control strategy, and can fully consider the deformation of the workpiece in the process of precision hardware machining, and formulate control codes according to the actual situation of the machining to improve the control accuracy of CNC machining machine tools. As an enterprise, when choosing CNC machine tools, it must meet the precision requirements of precision hardware processing workpieces, and purchase machine tools reasonably. In the case of high precision requirements, advanced control equipment should be selected.

2) Precision hardware processing fault diagnosis system

If the precision hardware processing fails, it will lead to the reduction of the processing control accuracy. Therefore, a CNC system with fault diagnosis must be selected in practice. Machining or other fault diagnosis modules can be used to alarm in time after the machine tool fails, and can quickly feedback the fault. information, enabling maintenance personnel to maintain timely and resolve problems quickly. At the same time, the precision hardware processing fault diagnosis system should be able to find out the deterioration of the processing accuracy, monitor the stability of the machine tool itself and the service life of the processing tool, so as to achieve all-round management.

3) Use reasonable tool machining error compensation control

The motion mode of the tool used in precision metal machining in multi-coordinate CNC machining is linear interpolation motion. Therefore, there are tool errors in the process of precision hardware processing, and some error compensation measures must be taken. Corresponding compensation can be made according to the machining shape, which can be fully utilized in the process of tool movement. Consider compensatory measures. At the same time, the corresponding compensation parameters are calculated according to the system setting, which is consistent with the machining system of the machine tool, and the most suitable machining control method is given.

4) System operator management system

The quality of the operator affects the accuracy of precision metal machining controls. Therefore, enterprises should establish a system operator management system, conduct quality assessments for all CNC machining operators, and work only after they have qualified professional knowledge assessments. At the same time, manage and control abnormal operator behavior and establish operating principles, requiring all operators to follow instructions. In addition, regular management operators carry out professional learning, so that these employees are exposed to the professional knowledge of the introduction of advanced equipment, so as to improve the precision metal processing ability and play a better role.

5) Improve machine maintenance management For CNC machining machine tools, it is necessary to carry out perfect maintenance management, timely maintenance of machine tools, and regular lubrication of parts

Lubricate to ensure that the machine maintains good contact between moving parts. In the application processing machine tool, it is necessary to check the machining accuracy and adjust it according to the accuracy deviation and the parameters of the machining center. At the same time, it is necessary to make necessary adjustments during the maintenance process, and test the machining accuracy with standard parts according to the machining state of precision hardware. Control the working environment of the machine tool to prevent too much dust from entering the machine tool and affect the normal operation of the machine. At the same time, it is necessary to regularly check the screens and filters of the pneumatic system and hydraulic system, and to replace the hydraulic oil in the hydraulic cylinder regularly.
