Surface quality is another aspect of machining accuracy. It consists of the surface finish and the physic mechanical state of the surface layer. It affects the proper functioning and service life of the parts Surface Finish Machining accuracy is expressed quantitatively in machining error. Surface finish is expressed quantitatively in surface roughness. The surface roughness on a machined workpiece surface is caused primarily by the geometrical factors(cutting tool geometry and cutting
There are two basic methods of generating process manufacturing gear teeth,the generating process and the forming forming process process. When a gear tooth is generated, the workpiece and the grinding cutting or grinding tool are in continuous mesh and the tooth form is mesh
