tools used for turning

In turning processing, especially for finishing, how to choose a tool? Determine the entering angle of the tool Among the entering angles of conventional tools, the ones suitable for finishing are generally between 90° and 95°, especially 91°, 93°, and 95° which are most used. The entering angle of close to 90° makes the cutting force follow the axis of the workpiece, and no vertical force is applied to the workpiece to avoid vibration and deformation (thin-walled parts processing is especially important). The entering angle is generally guaranteed on the tool bar. Determine the angle of the tool tip and select the tool shape Generally, our commonly used blade forms mainly include: Round blade (beginning with R), 90 degree square blade (beginning with S), 80 diamond blade (beginning with C), 80 degree convex triangular blade (beginning with W), 60 degree triangular blade (beginning with T), 55 degree diamond blade (beginning with D) ), 35 degree diamond blade (beginning with V). These tool shapes basically cover more than 90% of conventional turning inserts. These types of inserts are arranged in terms of tool strength: R, S, C (W), D, V. R blade has the highest strength and V the lowest. But the higher the strength, the greater the resistance and the greater the risk of vibration. Therefore, we often choose R, S, C (W) for roughing. For finishing, we will choose D and V. The profiling ability required for finishing is also the best for V and the worst for R. Determine the rake angle and back angle of the tool The negative rake angle tool has good rigidity and is not easy to chip, which is suitable for rough machining, while the positive rake angle blade cuts lightly and is more suitable for finishing. There is a matching relationship between the rear angle and the rake angle. Generally, the negative rake angle blade is basically a 0 degree rear angle. And the positive rake angle insert has 5°(B), 7°(C), 11°(P) three commonly used clearance
