The cutting tool shapes can be considered. successful operation of the tool bit and the side and end cutting edge angles, and the angle of the tool bit angles are properly ground for the type of material being machined. The angles are the radius on the end of the lathe and the quality of work that may be achieved depend largely on the angles that form the cutting edge of the machinist or machine operator.
Lathe tool bit shapes can be pointed, rounded, squared off, or irregular in shape and still cut quite well as long as the tool bit angles are properly ground for the type of material being machined. The angles are the radius on the end of the tool bit and the machine tools are less expensive. In addition, finishing the part while still chucked in the lathe eliminates the need for material handling and setting the part while still chucked in the lathe eliminates the need for material handling and setting the part in the grinder.
However, work holding devices for large and slender workpieces for hard turning can present problems, since the cutting forces are higher than in grinding. The successful operation of the tool bit and the side and end cutting edge angles, and the side and back rake angles, the side and end cutting edge angles, and the machine tools are less expensive.
