Gantry System with Axes of Orientation

 

A gantry cutter is a gantry system with a rotary axis that is equipped with a cutting tool.

The configuration of a gantry system with a rotary axis is similar to that of a simple gantry system. However, these systems also have a rotary axis where the vertical cutting unit is attached.

When you use a gantry system with a rotary axis, you have to use the SMC_TRAFO<n>_GantryCutter<n> POUs instead of SMC_TRAFO<n>_Gantry<n>. Then, the rotary axis is controlled in such as way that it is oriented along the current path tangent.

The gantry cutter POUs have the following additional inputs:

• DriveR: Rotary axis that has to be used with a period of 360°

• dOffsetR: Offset of the rotary axis

• iDirectionR: Direction of rotation

The POUs for inverse transformation also have to include the vector of the current path tangent (v) that is an output of the interpolator.
