Basic principle of NC machining

The basic principle of NC machining is to control the movement and machining process of machine tools by computer programs. Specifically, according to the material, machining requirements and machine tool characteristics of the workpiece, the programmer compiles a machining program containing information such as tool path and cutting parameters. These programs are transmitted to the numerical control system through the input device, and the numerical control system analyzes and controls the moving parts of the machine tool (such as spindle and feed shaft) to move according to the predetermined trajectory, thus realizing the machining of the workpiece.

Machining process of NC machining

The processing flow of NC machining usually includes parts analysis, process planning, programming, machine tool debugging, machining implementation and quality inspection. In the part analysis stage, it is necessary to analyze the shape, size and material of the workpiece in detail to determine the processing difficulties and key points. In the process planning stage, reasonable machining sequence and cutting parameters are formulated according to the analysis results of parts. The programming stage is to transform the process planning into a processing program that can be recognized by the computer. The debugging stage of machine tool is to calibrate and test run the machine tool to ensure that the machine tool is in the best working condition. The processing implementation stage is the actual processing according to the processing procedure. Finally, the processed parts are inspected through quality inspection to ensure that they meet the design requirements.

Key technology of NC machining

The key technologies of NC machining include NC programming, tool selection and cutting parameter optimization. NC programming is the core of NC machining, which is directly related to machining efficiency and quality. Tool selection needs to choose the appropriate tool type and specification according to the material and processing requirements of the workpiece. Cutting parameter optimization is to achieve the best balance between machining efficiency and machining quality by adjusting cutting speed, feed and cutting depth.

Practical application of NC machining

Numerical control machining technology is widely used in practice. Taking the automobile manufacturing industry as an example, NC machining technology is widely used in the machining of key components such as engine cylinder block, cylinder head and crankshaft. Through NC machining technology, these parts can be machined with high precision and efficiency, and the overall performance and reliability of the automobile can be improved. At the same time, NC machining technology also plays an important role in the field of mold manufacturing. Through CNC milling, CNC EDM and other technologies, molds with complex shapes can be manufactured to meet the production needs of different products.
