ABSTRACT:
A gaging system especially adapted for use with a press brake and which employs a direct drive servo motor directly coupled to a movable table and linear encoder directly coupled to the movable table for providing electrical output signals representative of actual gage position. One or more gage stop assemblies are supported by the movable table and are manually adjustable to both coarse and fine degrees. Closed loop servo control of gage position is provided to control motor drive in response to actual position signals derived from the linear encoder.
