How do Professional CNC Machining Manufacturers Carry Out Quality Control?

VMT is a CNC machining manufacturer integrating R&D, production and sales, including CNC lathe machining, computer gong machining, five-axis machining, CNC machining, lathe parts, non-standard CNC machining, CNC lathe machining, CNC precision machining, Aluminum CNC machining customization and other services, and has a complete and scientific CNC machining quality management system. We use high quality machines for precision CNC milling and turning, precision EDM, precision grinding and a range of other tools in-house, using alternating current to stabilize shop temperatures. Combined with the experience and qualifications of our engineers and rigorous inspection of CNC machining machines and processes, this ensures consistent quality even in the most demanding situations. We control the CNC machining quality from five key links, namely the design link of the CNC machining scheme, the programming link, the simulation inspection link, the application link of the CNC machining quality control methods and tools, and the establishment of the CNC machining technical team. The following five key aspects of the in-depth study.

1. CNC Machining Design Scheme

The CNC machining design plan mainly includes the following contents. The first is to determine the type, size and model of the parts to be processed by data, and to generate the parts drawings. At the same time, the processability in the CNC machining is analyzed to determine the process route of the CNC machining. , and then clarify the contents of each process of CNC machining, and finally select the CNC parameters and machining tools. Compared with ordinary machine tool processing, CNC machining is similar in design principle, but the control method of CNC machining is different, it has a higher degree of automation, and the cost of CNC equipment is relatively high. Therefore, its process design should be more rigorous, the design content should be more specific, and it needs to have strong adaptability.

2. Programming During CNC Machining

In CNC machining, the programming of the program is also a key link. The instruction code in the program directly affects the output result, and has a key impact on the CNC machining quality of the parts. When programming the program, it should be ensured that the mathematical model used in the CNC machining process of the part is accurate, and the coordinate system should be accurately defined. At the same time, the attribute parameters, tool points and safety planes in the CNC machine should be correct setting. In addition, it is necessary to reasonably arrange the various processes and processing sequences in the CNC machining plan, and correctly select the tool type, tool path and cutting amount, and the use of command letters must be able to accurately grammatical formats in the CNC system of the machine tool. describe. When choosing the cutting parameters, the cutting characteristics of the tool itself, the processing characteristics of the material of the CNC machined parts, the machining allowance of the parts, and the cutting characteristics of the machine tool should be comprehensively considered. Finally, in the process of CNC machining, it is necessary to ensure that the CNC machining path of the part's tool does not have overcut, interference, collision and other phenomena.

3. Simulation Inspection Link

Simulation inspection is also a key link in CNC machining quality control. The content of simulation inspection mainly includes physical simulation and geometric simulation. In terms of physical simulation, people mainly through the simulation analysis of the physical phenomenon generated during CNC machining to check whether the physical phenomenon is reasonable. In terms of geometric simulation, the application of virtual reality technology or three-dimensional display technology can be used to carry out realistic geometric simulation of the entire process of CNC machining, so as to determine whether geometric interference or collision problems will occur when the machine tool is moving in the CNC program, as well as the tool Check whether the running track is correct or not. It can be said that the simulation inspection link is an important guarantee to ensure the safety and accuracy of CNC machining. This link can effectively avoid the occurrence of various problems in the processing process, so that CNC machining becomes more scientific, efficient and reasonable.

4. CNC Machining Quality Control Methods and Tools

In the application of CNC machining quality control methods and tools, people should implement quality planning according to the quality control system and its processing flow, determine the quality control points and index characteristic values ​​in each process, and then conduct actual investigations on the capabilities of each process. Analyze and determine the relevant factors affecting the development of the process. Then, prepare quality control documents such as process management points and quality tables, so as to dynamically collect the quality indicators in the process of data processing in real time and comprehensively, so that the quality control method can organize, analyze and evaluate these quality indicator data. Finally, draw a conclusion, and implement intervention control on the leading factors that affect the quality in the actual CNC machining process, so that the quality control goal can be finally realized.
