Step 1: Design 2D or 3D drawing through CAD software.
Through the displacement control system of CNC machines, the information is transmitted to the driver to drive the motor to cut the designed parts. After the program instructions are input into the memory of the CNC system, the computer compiles and calculates. The generated file is loaded into the CNC machine tool for workpiece processing. The motion instructions and other auxiliary instructions required in the machining process are converted into the format that can be read by the NC system through the post processor of the CNC machine.
Computer aided manufacturing software analyzes and designs the model and calculates the motion instructions in the CNC machine machining process. In modern CNC operating system of CNC machine, the design of workpiece highly depends on software such as computer aided design (CAD) and computer aided manufacturing (CAM). CNC controller of the CNC machine can read G-code and start machining.
The full name of CNC is computerized numerical control. Cam stands for computer aided manufacturing, which is used to generate G-code. CNC machines are also known as CNC machinery, CNC machine tools, computer-controlled machine tools, C and C machines, CNC processing tools, CNC kits, CNC mask machines, CNC equipment, CNC power tools, CNC cutting machines, digital machines, CNC cutting machines.ĬAD refers to computer aided design, which is used for 2D or 3D workpiece or 3D design. It controls the automatic execution of the operation instructions of the machine tool, with high speed, high precision, high efficiency and repeatability. If the CNC program is properly prepared and the computer is properly programmed, the same part can be copied multiple times with the same accuracy. The new machine tools in CNC programming enable the industry to continuously produce parts with precision unimaginable a few years ago. CNC refers to the idea that machine tools are controlled by computers rather than manually by mechanics. A CNC machine consists of frame, numerical control controller, spindle, gantry, numerical control operating system, numerical control software, switch, rack and pinion are composed of motor, driver, T-slot worktable or vacuum worktable, ball screw, guide rail, power supply, collet, vacuum pump, limiter, etc. It is suitable for hobbyists, amateurs, small enterprises, small stores, family enterprises, home stores, school education and industrial manufacturing. CNC machine is an automatic computer numerical control machine tool with multiple functions such as cutting, engraving, carving, milling, drilling, slotting and turning.
