CNC CNC machining is an advanced processing technology in today's machinery manufacturing industry, which inputs the CNC program of the machined parts to the CNC machine tool, and the machine tool automatically processes the workpiece after receiving the CNC program. CNC machining technology can effectively solve the complex small and medium-sized batch changeable processing scheme of hardware parts, and meet the needs of modern production.
The CNC machining process involves tool selection, cutting data, and toolpaths. CNC machining process is the core content of CNC programming. Choose a CNC program with less machining time and the smallest toolpath to get a high-efficiency and high-quality product. CNC machining technology can be divided into rough machining, corner clearing, and finishing.
When roughing, a larger tool should be selected to quickly remove a large number of workpiece allowances in the maximum power of the machine tool to roughen precision parts. The principle of tool selection is mainly based on whether the chamfered arc surface of the product is too small to consider, and after selecting the tool, the knife length is determined. In principle, the tool length should be greater than the machining depth.
The tools we use are all angled, and generally need to be angled on the step axis. We mill a retract where the corners need to be cleared. The advantages of this are: first, it is convenient for the grinding shaft of the grinder to remove the sand wheel as soon as possible, which will not grind to the end face and affect the length, and second, when the assembly is fully in contact with the end face, the end face runout will be smaller.
