Value of rake angle usually varies in between –15º and +15º; however, it may reach up to ±30º in some cases. In abrasive cutting, rake angle of abrasives (such as abrasives of grinding wheel) can even go beyond ±60º. Presence of nose radius can also change rake angle and in such scenario effective rake is considered.

The angle of inclination when viewed from the side or front is the angle of the insert seat or pocket in the toolholder, from front to back. This inclination can be either positive, negative, or neutral. The cutting tool's rake angle is the angle between the cutting edge and the cut itself. It may also be positive, negative, or neutral.

With increased angle, quicker rounding occurs, but it also weakens the blade rigidity. The most common top angle used in centerless grinding is 30 degrees. As the diagram below indicates, lower angles are used when grinding heavy workpieces, which help minimize vibration. Workrest top angles typically range from 45 degrees down to 20 degrees.

So you can affect how a grinding wheel performs by changing regulating wheel inclination and regulating wheel RPMs. Parts that have a high diameter-to-length ratio, such as bearing rings, should have a lower regulating wheel angle of inclination to help keep the parts stable as they travel through the grind zone.

Cutting edge inclination indicates inclination of the rake face. During heavy cutting, the cutting edge receives an extremely large shock at the beginning of each cut. Cutting edge inclination keeps the cutting edge from receiving this shock and prevents fracturing. 3°–5° in turning and 10°–15° in milling are recommended.
