Selecting Appropriate Cutting Speed, Feed Rate, and Cutting Depth for Turning

In order to ensure the highest possible processing speed while meeting quality requirements, it is necessary to select the appropriate cutting speed, feed rate, and cutting depth based on the material and shape of the workpiece. Turned Parts is a common metal processing method that removes excess material from a workpiece by rotating a cutting tool relative to the workpiece, resulting in a part with the desired shape and size. When determining the cutting speed, feed rate, and cutting depth, it is necessary to fully consider the characteristics and shape of the material to ensure processing efficiency and quality. This article will discuss in detail how to select the appropriate cutting parameters from several aspects.

Cutting speed refers to the number of times the cutting tool comes into contact with the workpiece per unit time, and can also be understood as the operating speed of the tool. Selecting the appropriate cutting speed can improve processing efficiency, but if the speed is too fast, it may cause the tool to overheat, accelerate blade wear, and even cause the workpiece surface to become rough. To select the appropriate cutting speed, it is necessary to determine it based on the hardness and machinability of the material. The higher the hardness of the material, the generally lower the applicable cutting speed; while materials with good machinability can use higher cutting speeds.

Feed rate refers to the distance the cutting tool moves in the axial direction per unit time. Selecting the appropriate feed rate can improve processing efficiency and also ensure that vibration and excessive cutting force are not easily generated during cutting. The selection of feed rate needs to consider the hardness and machinability of the material, as well as the strength and stability of the tool. In general, harder materials should use a smaller feed rate; materials with good machinability can use a larger feed rate.

Cutting depth refers to the angle between the tool and the workpiece, i.e. the depth of the tool's penetration into the workpiece. Selecting the appropriate cutting depth can improve processing efficiency, but too large a cutting depth may cause the tool to wear faster and the surface quality to deteriorate. When selecting the cutting depth, it is necessary to consider factors such as the hardness, machinability, and strength of the material. Generally speaking, harder materials should use a smaller cutting depth; materials with better machinability can use a larger cutting depth.

In order to ensure the highest possible processing speed while meeting quality requirements, we need to select the appropriate cutting speed, feed rate, and cutting depth based on the material and shape of the workpiece. When selecting cutting parameters, it is necessary to fully consider the characteristics of the material, including hardness and machinability, as well as the strength and stability of the tool. Only by selecting the cutting parameters reasonably can the processing efficiency be improved and the processing quality be guaranteed.
