SIZING THE WORK SUPPORT In order to find the size of work support needed, you must first determine the total load the work support must withstand. This load is based the following factors: The amount of anticipated force being exerted on the work support due to the operation being performed against it. The amount of force being applied over the work support by the clamp reacting on the piece-part. The force exerted by the operation being performed combined with the clamp force being applied must not exceed the rated capacity of the work support. As the operational forces are anticipated , some margin of safety should be incorporated by the designer. Additionally, if the work support is subjected to severe vibrations or “hammering” such as those generated from an interrupted cut, an additional safety factor needs to be incorporated. Using the following work support selection chart, find the anticipated capacity for your application in the left hand column. Follow across the chart to the right until your application load intersects the anticipated hydraulic operating pressure of the system. Choose the size of work support needed from the curve that intersects this point or from the nearest curve above the required point.
