For example, engine block, transmission housing, etc., CNC processing can create a complex mold cavity to meet the molding requirements of metal parts to ensure that the use of molds can be manufactured to meet the technical requirements of the parts.

CNC machining quality control

Quality control before processing

On the one hand, do a good job of material and tool selection and control. Choose high-quality materials that meet aerospace industry standards. Examples include aluminum alloys, titanium alloys, stainless steel, and composites. We inspect incoming raw materials for quality. This includes analyzing their chemical composition and testing their mechanical properties. The goal is to ensure the material meets the processing requirements. When selecting machining tools, choose suitable high-performance tools to ensure the stability and precision of the machining process. But, the parts have certain characteristics and requirements. So, the process route and cutting parameters should fit them.

Quality control during machining

We monitor the operating parameters of the machine tool in real time. These include cutting speed, feed rate, and cutting force. We use them to check the stability and reasonableness of the machining process. We make timely adjustments and optimizations based on the results of the first part’s machining. Adopt on-line measurement system, such as on-machine measurement probe, to carry out real-time measurement of the parts under processing, and discover the dimensional deviation in time and make adjustments. In production, the products are sampled at a certain percentage. This is to check the consistency and stability of the processing quality.

Quality control after machining

After processing, measure the parts using equipment that fits their size and accuracy. Use the equipment the drawings specify. For example, the use of CMMs on machined parts. They test size and shape to ensure the parts meet the design requirements. After the inspection, the results are evaluated.
