The "positive" direction for rotations in benders is NOT standardized. It is important to understand how to determine rotation directions to avoid confusion through mirror-imaging parts accidentally.
- The direction of rotation can be indicated with a CW or CCW direction of rotation from the viewpoint of a viewer at the front of a bender looking toward the rear of the bender.
- When a bender collet rotates CCW to rotate positive, then it uses the American industry standard, the standard for our VTube software. In this case, +90 would rotate the chuck 90 degrees CCW.
- When a bender collet rotates CW to rotate positive, then it uses the non-American industry standard, the opposite of the VTube software. In this case, +90 would rotate the chuck 90 degrees CW.
The engineering community uses a simple right-hand/left-hand rule to designate which way an axis spins positive.
This BobCAD-CAM illustration demonstrates the RIGHT-HAND rule. In this "right-hand rule" illustration:
