56 I Operating Instructions
I - 3 Milling Specific Oper
ations
 The contour view show the position of the tool relative to the milling
surface. When the crosshair representing the tool is on the line
representing the surface, the tool is in position. The tool crosshair
remains fixed in the center of the graph. As the table is moved, the
surface line moves.
 Press the END soft key to exit the milling operation.
Tool radius compensation is applied based on the radius of
the current tool. If the plane selection involves the tool axis,
the too tip is assumed to have a ball end.
The tool offset direction (R+, or R-) is applied based on the
tool position. The operator must approach the contour
surface from the appropriate direction for tool
compensation to be correct.
