It shows how to create a CAM table inside a program, and use the CAMBOX
motion command.
The profile used is the COS square one. This is a quite typical profile for
feeder-type applications as:
• The motion provides a smooth acceleration without sudden acceleration
changes, so the material slip is minimized
• It gives a fast deceleration so the cycle time is reduced. During
deceleration there is no material slip and the friction helps to the stop to
zero.
