Positive direction rotations in benders are NOT standardized. It is important to understand how to determine rotation directions to avoid confusion through mirror-imaging.
- 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.
The robotics and engineering community uses a simple right-hand/left-hand rule to designate which way an axis spins positive. For example, this is an image from the Bobcad-CAM site:
In this "right-hand rule" illustration:
- You are standing in the front of the bending looking toward the back.
- Hold your right hand up in front of you.
- Point the thumb of your right hand toward your face.
- The arrow centerline is the centerline of the tube coming out of the collet.
- The direction of the curl of the rest of your fingers represents the direction of a positive rotation.
- Therefore, the right-hand rule shows indicates that positive rotates CCW.
Note that European and Asian benders usually follow the LEFT-HAND rule.
