Compensation for real workpiece surface

Distance control compensates for deviations between the actual workpiece surface and the theoretically assumed surface.

There are two different options for compensation. Depending on the application, they are selectable in the NC program when distance control is activated.

  1. In tool direction (mode = ECS): Height deviation is compensated by tracking the tool head in the tool direction. In this mode, the cutting curve orientation is maintained despite the height offset. This is essential for a (pipe) feedthrough, for example.
  2. Orthogonal to tool surface (mode = MCS): A height deviation is compensated by tracking the tool head orthogonally to the surface. In this mode, the projection (top view) of the machining operation remains identical, i.e. the shape is not distorted but only offset in height.
