3. Cutting test method The test device used in this test is shown in Figure 1. The compressed gas produced by the compressor is sent to the cold air generating device, and the instrument and switch are adjusted to the required temperature, and then sprayed by the nozzle between the rake face of the tool and the chip. This acts as a chip evacuation and cooling cutting zone. In sub-dry cutting, the additive is dripped with the cold wind between the rake face and the chip. In this study, continuous cutting was used as the research object. All the same materials and the same type of test were completed on the same test piece; the same material was used in the cutting stability test. Segmented continuous cutting is done to increase the comparability of similar tests. 4. Test content When cutting GCr12, take ap=0.75mm, f=0.1mm/r, and get Figure 2. 1.
