Abstract
An electronic hollow grinder bevel angle indicator wherein a microprocessor calculates the grinding bevel angle that will be obtained when a tool is placed flat upon a tool rest and presented to the periphery of a rotating grinding wheel. The calculated bevel angle is the acute angle of intersection between the tool rest plane and a plane tangent to the grinding wheel periphery at the line of intersection between the grinding wheel periphery and the tool rest plane. The microprocessor also calculates the air-gap between the tool rest and grinding wheel, and warns the operator when the air gap exceeds a specified safety threshold.
