Delete contour element
Use the cursor keys to select the element you wish to delete. The selected contour symbol
and associated contour element in the programming graphic are highlighted in red. Then
press the "Delete element" softkey and confirm the query.
Undo an input
By selecting the "Abort" softkey you can return to the main screen without transferring the
last edited values to the system.
Contour symbol colors
The meaning of the symbol colors in the contour chain on the left of the main screen is as
follows:
Icon
Significance
Selected
Symbol color black on a red background -> Element is defined geometrically
Symbol color black on a light yellow background -> Element is not defined
geometrically
Not selected
Symbol color black on a gray background -> Element is defined geometrically
Symbol color white on a gray background -> Element is not defined geometrically

Programming example, surface grinding
Introduction
When programming free contours, for surface grinding it usually involves dressing contours.
In this case, under certain circumstances the dressing contours are machined using multiple
tools (dressing tools). The X position must be programmed in the DIN program at X0, as the
axis is not included in the contour path.
The approach also takes place outside the contour, as the approach movement should be
completely realized using G0!
The commands for continuous-path mode (G64) and tool nose radius compensation
(G41/G42) must be inserted manually.
Note
When programming the free contour, the display of the coordinate system is determined by
display machine data MD290 CTM_POS_COORDINATE_SYSTEM.
