2022 01 21 Mild steel is a material with low hardness and high viscosity, and its cutting performance is poor. In order to make the surface roughness of CNC machined holes reach Ra=1.6m after finishing, most of them use high-speed steel reamers and low-speed reamers to complete the hole processing through three processes of drilling, expanding and expanding.

VMT 2022 01 19 At present, metal CNC machining castings have been widely used in the manufacturing industry. This casting process dates back 6,000 years and is still used today to make complex and large custom metal CNC machined parts. With the development of the foundry manufacturing industry, the CNC machining process of metal castings is automated, the cost is low, and the processing is more complex, large and small.

VMT 2022 01 19 RTCP, in the high-end five-axis CNC machining system, considers RTCP as the center point of the rotating tool, which is what we usually call the tool nose point tracking function. In five-axis CNC machining, when the trajectory of the tool head point and the attitude between the tool and the CNC machined part are tracked, the rotary motion will generate additional motion of the tool cusp.
