Principles of Modern Grinding Technology

Chapter 9 - Cost Reduction. Pages 145-161. Publisher Summary. The energy consumed in the grinding process is spent on deforming and cutting new surfaces in the workpiece material. The new surface area produced is therefore a measure of the energy required. The new surface area produced is closely related to the surface area of the uncut chips.Get price
