Limitations, errors and checks

The CNC performs a number of checks to prevent operational errors. An extract of the checks relevant for die sinking is listed below:

• When the escape channel is activated, the radius must be zero [ ID 50916].
• The radius is unequal to 0 when the orbit channel approaches the geometry [ID 50922].
• Escape/restart position not found [ID 50926].
• At the end of the path in the escape channel, the X/Y position must be zero [ID 50931 and ID 50932].
• The escape channel must be activated before the orbit channel is activated in order to mark the geometry for erosion on the path [ID 50933].
• The geometry for erosion on the path must be identical in the down and escape channels [ID 50950, ID 50934, ID 50951].
• The geometry for erosion on the path must be defined in the escape channel before the NC command #TRACK CHAN ON [Escape] [ID 50949].
• No single axis may be moved after erosion on the path [ID 50839].
• A CS may not be active in the escape channel, neither at the start nor at the end of the geometry for erosion on the path [ID 50945 and ID 50946].
• It is not possible to change the CS within the geometry for erosion on the path. It is only possible to change the CS after the start or end of the geometry [ID 50947].
• The position in the down channel changed during an escape motion during erosion on the path [ID 50956].
• A change of CS in the down channel is only possible when the orbit channel is deactivated. If a change of CS is necessary in the down channel, the orbit channel must be deactivated, the CS change must be executed in the down channel and finally the orbit channel is reactivated with the correct CS [ID 50984].
• The specified start position for erosion of the path of the down channel is not within the geometry defined in the escape channel [ID 50995].
• When the points for the point strategy are defined, the specified Y coordinate may not be less than zero and the specified Z coordinate may not be above the end of the geometry for erosion on the path [ID 51006 and ID 51007].
• Before #TRACK CHAN of the orbit channel is deactivated, the channel interface must first be deactivated [ID 51013].
• Before #TRACK CHAN of the escape channel is deactivated, the channel interface must first be deactivated [ID 51014].
• Radius is not 0 before a complete orbit geometry is decoded [ID 51019].
• The coupled master channel moves during channel initialisation of the slave channel [ID 51021].
• The escape channel shifted in the geometry for erosion on the path due to the sliding motion of the down channel [ID 51024].
• When #TRACK CHAN ON [ESCAPE] is activated, no commanded escape strategy of the master channel was found [ID 51033].
• During the escape strategy of the angle bisector, the geometry in the down channel exceeded 180 degrees [ID 51031].
