General information

Application
A grinding operation involves both machining of a workpiece and dressing of the grinding
wheel. These processes can take place in the same channel or in separate channels.
To allow the wheel to be dressed while it is machining a workpiece, the machine must offer a
function whereby the reduction in the size of the grinding wheel caused by dressing is
compensated on the workpiece. This type of compensation can be implemented by means of
the "Online tool offset" (Continuous Dressing) function.
Dressing during machining process
To allow machining to continue while the grinding wheel is being dressed, the reduction in
the size of the grinding wheel caused by dressing must be transferred to the current tool in
the machining channel as a tool offset that is applied immediately.
This parallel dressing operation can be implemented by means of the "Continuous Dressing
(parallel dressing), Online tool offset" function.
Note
The online tool offset may only be used for grinding tools.
