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 und 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 offset curve of this block with a circle whose
center point coincides with the end point of the noncorrected 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.
