Numerical control CNC Machining is a manufacturing process that uses a computer-controlled machine to manufacture parts from raw materials. Numerical control CNC machining process flow mainly includes the following steps: Analyze the drawings and formulate the process plan: According to the requirements of the drawings, analyze the processing characteristics, determine the processing plan, select the appropriate tools and fixtures, and determine the cutting parameters and machining route. Programming: According to the process plan, use numerical control programming software to write the machining program. The program should include all the necessary machining steps, including cutting path, tool selection, cutting parameters, etc. Simulation: Before machining, use numerical control simulation software to simulate the machining program to check the correctness and feasibility of the program. Machine tool operation: Transmit the prepared machining program to the numerical control machine tool, start the machine tool according to the operating procedures, and process the workpiece. Quality inspection: After the processing is completed, the workpiece is quality inspected to ensure that it meets the drawing requirements. If necessary, it can be corrected or reprocessed. Clean up the site: After the processing is completed, clean up the machine tool and the site to keep it clean and safe. It should be noted that the specific steps of the numerical control CNC machining process flow may vary depending on the different processing requirements and machine types. In actual operation, it needs to be adjusted and optimized according to the specific situation.
