It is possible to insert chamfering and corner rounding blocks automatically bet-
ween the following items:
-- Linear interpolation and linear interpolation blocks
-- Linear interpolation and circular interpolation blocks
-- Circular interpolation and linear interpolation blocks
-- Circular interpolation and circular interpolation blocks
Format
, C...; Champfering
, R...; Corner rounding
Explanations
A chamfering or corner rounding block is inserted whenever the above specification
is added to the end of a block that specifies linear interpolation (G01) or circular
interpolation (G02 or G03). It is possible to specify blocks applying chamfering and
corner rounding consecutively.
