This military spec bender chart data chart can converted by VTube-STEP and VTube-LASER in the LRA grid section of the Part Data menu.
About this Bender Data Specification
- This bender data spec uses ABSOLUTE LENGTHS between bends as if they were derived from a tape-measure attached to the Feed axis of a bender. CONRAC benders use this style of length data to indicate where the bends begin.
- The bender data uses ABSOLUTE ROTATION data (twist angle between the planes of the bends). It is absolute because it always depends on the rotations in all preceding bends accumulated. The dial on an absolute rotation spindle reads from 0 to 360. The dial puts all rotations at the top of the dial. It starts with "0" at the top of the dial.
- Although it seems to be ambiguous in the specification, most military prints assume DRAW bending versus COMPRESSION bending - which means the LENGTH values move the carriage so that the tube is positioned at the start of each bend (for clamping and drawing around the die) rather than the end of each bend (for clamping with rollers or wipers and compressing around the die).
