Block N30 selects the ZX plane (G18) and positions the tool at the
starting point (30,90).
Block N31 turns RTCP on.
Block N32 contains a movement to point (100,20) and a tool
orientation from 0º to -90º. The CNC interpolates the X, Z and B axes
in such a way that the tool is being oriented along the movement.
Block N33 contains a circular interpolation to point (170,90)
maintaining the tool perpendicular to the path at all times.
At the starting point, it is oriented to -90º and at the endpoint, it must
end be 0º.
The CNC interpolates the X, Z and B axes maintaining the tool
perpendicular to its path at all times.
Block N34 moves the tool to point (170,120) maintaining the
orientation of 0º.
Block N35 cancels RTCP.
Example b) Circular interpolation with tool perpendicular to
its path
