Answer :
The purpose of a work rest on a pedestal grinder is to support the work. Therefore, the correct answer is B) Support the work.
A pedestal grinder is a type of grinding machine used for sharpening and finishing metal parts. In the context of a pedestal grinder:
Work Rest Purpose : The work rest is an integral part of the grinder which provides a surface on which the user can place the part being ground. This support ensures that the workpiece is stable and doesn't get pulled into the grinding wheel, allowing for more precise and safe operation.
Adjustment : The work rest should be adjusted to maintain an appropriate gap between the wheel and the work rest. Typically, this clearance should not exceed 1/8 inch (about 3 mm) to prevent the workpiece from being jammed between the rest and the wheel, which could cause accidents.
Functionality : By supporting the workpiece, the rest allows the user to apply consistent pressure on the part against the grinding wheel. This helps in achieving a uniform edge or surface finish.
Overall, the work rest is a vital component for safety and precision work when using a pedestal grinder.
