1. Field of the Invention
This invention relates to punch presses, and more specifically to gaging used to locate a workpiece with respect to the die and hence with respect to a previously prepared program of punch press operation.
2. Prior Art
Various types of gaging have been provided on punch presses to orient a workpiece with respect to a program of press operations. The problem is to get an exact precise dimension of predetermined size between the gaging surface and the centerline of the die. For example, at typical dimension is 48.000 inches plus or minus 0.0005 inch. Thus with such a dimension, the entire range of permissible locating errors is only one part in 48,000. During usage, wear becomes an immediate problem necessitating removal, grinding and shimming. Further, prior X-axis gaging has been so constructed as to be virtually specialized for a specific punch press construction.
