G461/G462 
In order to enable the solid machining of inside corners in certain situations with the 
activation and deactivation of tool radius compensation, commands G461 and G462 have 
been introduced and the approach/retraction strategy has thus been extended for tool radius 
compensation. 
•  G461 
If no intersection is possible between the last TRC block and a previous block, the control 
calculates an intersection by extending the compensation curve of this block with a circle 
whose center point coincides with the end point of the non-corrected block, and whose 
radius is equal to the tool radius. 
•  G462 
If no intersection is possible between the last TRC block and a previous block, the control 
calculates an intersection by inserting a straight line at the end point of the last block with 
tool radius compensation (the block is extended by its end tangent). 
Changing from G40 to G41/42 
The change from G40 to G41/G42 and vice versa is no longer treated as a tool change for 
tools with relevant tool point direction (turning and grinding tools). 
Tool compensation environments 
Functions, which enable the following actions in relation to the current states of tool data, are 
available in SW 7.1: 
•  Save 
•  Deletion 
•  Read 
•  Modify 
Some of the functions were previously implemented in measuring cycles.  
They are now universally available. 
A further function can be used to determine information about the assignment of the tool 
lengths of the active tool to the abscissa, ordinate and applicate.
