How to control chip during turning milling compound machining
In turning milling combined processing, the hardness of the chip increases, the plasticity decreases and the performance becomes brittle after the chip is severely deformed in the deformation zone. In the process of chip discharge, if the strain of a part exceeds the fracture strain value of the chip material, the chip will break when it encounters obstacles such as the tool flank, the workpiece transition surface or the surface to be machined.
The greater the brittleness of the workpiece material (the smaller the fracture strain value), the greater the cutting thickness, and the smaller the cutting curl radius, the easier the chip will break. The following measures can be taken to control chips:
1. Chip breaking groove is adopted. By setting the chip breaking groove, a certain restraint force is exerted on the chips in the flow, so that the chip strain increases and the chip curl radius decreases.
2. Change the tool angle. Increasing the main deflection angle of the tool will increase the cutting thickness, which is conducive to chip breaking. Reducing the rake angle of the tool can increase the chip deformation and the chip is easy to break. The cutter inclination can control the flow direction of the chip. When the blade inclination is positive, the chip is often broken by the rear cutter face after curling to form C-shaped chip or flows out naturally to form spiral chip; When the blade inclination angle is negative, the chip often breaks against the machined surface after curling to form C-shaped chip or 6-shaped chip.
Adjust the cutting amount. Increasing the feed F increases the cutting thickness, which is beneficial to the chip; However, increasing F will increase the roughness value of the machined surface. Reducing the cutting speed appropriately will increase the deformation, which is beneficial to chip breaking, but it will reduce the material removal efficiency. Therefore, the cutting parameters must be properly selected according to the actual conditions of turning milling in Dongguan.
