How To Choose The Cutting Amount Reasonably?

Selecting a reasonable cutting amount is a very important part of the cutting process. Cutting amount are not only important parameters that must be determined before machine tool adjustment, but also have a very important impact on machining quality, machining efficiency and production cost. When selecting reasonable cutting amount, the machining properties must be considered. …

3 Measured Factors Of Machined Surface Quality After Cutting

The machined surface quality after cutting shall meet the machining requirements, including surface roughness, surface hardening degree, residual stress of machined surface, etc. (1) Surface roughness In cutting, due to knife marks, plastic deformation, vibration and friction, the machined surface will produce small peaks and valleys. The height and spacing of these small peaks and …

Basics About Tool Wear And Tool Life In Metal Cutting

The tool will wear gradually in the cutting process. When the tool is worn to a certain extent, the cutting force increases rapidly, the cutting temperature increases sharply, and even vibration occurs. At the same time, the dimensional accuracy of the workpiece decreases and the machined surface deteriorates obviously. At this time, sharpen or change …

Basics of Cutting Heat And Cutting Temperature In Metal Cutting

Cutting heat and the resulting cutting temperature are important physical phenomena in the process of metal cutting. A large amount of cutting heat increases the temperature of the cutting area, directly affects the wear and life of the tool, and affects the machining accuracy and surface quality of the workpiece. Cutting temperature can also be …

Strengthening Methods of Metal Materials: How Much Do You Know?

1. Deformation hardening (or strain hardening, work hardening) 1. Definition After yielding, with the increase of deformation degree, the strength and hardness of the material increase, and the plasticity and toughness decrease. This phenomenon is called deformation hardening or work hardening. 2. Mechanism With the progress of plastic deformation, the dislocation density increases continuously, so …
