A general term for a group of forces encountered in metalworking: tensile (stretching), compressive (squeezing), and shear (cutting). Tensile and compressive are the stresses encountered in the normal bending process. Shearing occurs only under circumstances of process failure.

A complete guide to the principles of the 4-Step set-up for tube-bending tools
This is a printable handbook showing how to implement in four standardized steps the “forward mandrel” set-up for rotary-draw tube-bending machines and establish process control over the so-called black art. The procedure is based upon the guiding principle that the tools make the bend and takes advantage of the inserted design of modern mandrel tooling.
