Methods for Selecting Cutting Tools and Optimizing Cutting Parameters for Ordinary Lathes

In lathe machining, the reasonable selection of tool materials, geometric shapes, cutting speed, feed rate, cutting depth, and other parameters are key factors in ensuring workpiece accuracy, surface quality, and machining efficiency. The material of the cutting tool needs to be selected based on the hardness, wear resistance, and other characteristics of the material being processed to ensure wear resistance and lifespan during the cutting process. The geometric shape of the cutting tool affects the distribution of cutting force and the quality of the cutting surface, so it is necessary to make appropriate design and selection according to the shape and requirements of the workpiece. The optimization of cutting parameters involves determining the optimal cutting speed, feed rate, and cutting depth. The selection of these parameters requires a comprehensive consideration of the properties of the tool and workpiece materials, the requirements for machining accuracy, and the balance of machining efficiency. Incorrect parameter selection may lead to tool wear, increased surface roughness, and decreased machining efficiency.
