With the continuous development of manufacturing technology, CNC (computer numerical control) technology plays a vital role in the field of parts processing. CNC parts processing customization provides enterprises with higher precision, efficiency and flexibility, and meets the needs of different industries for customized parts. However, to ensure the smooth processing of parts, many key issues need to be considered.
As a key technical document, the drawing provides the geometric size and shape information of the part, conveys the processing technology, quality requirements and design intentions, and is a communication bridge between the designer and the part manufacturer. It must include size and geometry requirements (linear size, angle, straightness, flatness, roundness, coaxiality, etc.), material specifications (material type, grade and performance parameters), tolerance requirements (allowable deviation range of each size), surface requirements (roughness, finish, mirror, coating), assembly requirements, quantity, graphic expression, part legend, and other necessary parameters.
The selection of suitable materials directly determines the performance, quality, cost, processing difficulty, mechanical properties, corrosion resistance, stability and other characteristics of the part. At the same time, the function of the part must match the application requirements. The correct material selection can ensure its normal operation in various environments.
The CNC machining process involves multiple links, including design, machining, quality control, etc., which requires close collaboration and information exchange between different teams. Clear communication and coordination can ensure that all links are consistent with the machining requirements, processes and quality standards. Regular communication helps to avoid information misunderstandings. Timely communication can adjust unreasonable machining plans and processes to deal with possible machining risks.
Different parts require different types of machine tools and cutting tools to meet their machining requirements, which can ensure the stability of the machining process and reduce the defective rate and scrap rate. Choosing advanced equipment can also improve production efficiency and shorten the machining cycle.
Reasonable process planning can reduce machining time, reduce costs, and ensure machining accuracy and surface quality. Planning the cutting path and machining sequence in advance can avoid repeated machining and unnecessary movement, and improve production efficiency. The selection and design of the clamping scheme also directly affects the machining stability and quality of the parts.
The machining parameter setting involves the adjustment of parameters such as cutting speed, feed speed, and cutting depth, which directly affects the machining quality, efficiency and tool life. Appropriate machining parameters can improve production efficiency and reduce machining costs while ensuring part quality. Different materials and geometries require different processing parameters.
Choosing the right fixture and clamping method can keep the parts stably fixed on the machine tool during processing to prevent movement, vibration and deformation. Whether it is a part with complex shapes or high-precision processing, fixing and clamping directly affect the quality of part processing.
Tool path planning can reduce unnecessary movement and repeated processing, maintain consistent cutting conditions, improve part surface quality, and reduce poor processing. In addition, you can also consider avoiding fixture interference and minimizing machine tool vibration to further improve processing accuracy.
