The grinding process is hard to observe directly due to its short contact time and small contact zone. Therefore, analyzing cutting forces and chip formation mechanisms can help to understand the grinding process better. The topography of abrasive material and kinematic motion between wheel-workpiece interfaces control the cutting forces.
