9.1 Tool radius compensation
Radius compensation is applied in the active work plane, previously
selected using functions G17 (XY plane), G18 (ZX plane), G19 (YZ
plane) or G20 (user defined plane).
Programming
The functions for selecting tool radius compensation are:
G41 Left-hand tool radius compensation.
G42 Right-hand tool radius compensation.
G40 Cancellation of tool radius compensation.
Depending on the type of compensation selected (G41/G42), the tool
will be placed to the left or to the right of the programmed path along
the machining direction and at a distance equal to the tool radius. If
no tool compensation is selected (G40), the CNC will place the tool
center right on the programmed tool path.
Being tool radius compensation active, the CNC analyzes in advance
the blocks to be executed in order to detect compensation errors
related to steps, null arcs, etc. When detected, the CNC will not
execute the blocks that cause them and the screen will display a
warning to let the operator know that the programmed profile has been
modified. A warning will come up for every profile correction made.
Properties of the functions
Functions G40,G41 and G42 are modal and incompatible with each
other.
On power-up, after executing an M02 or M30, and after an
EMERGENCY or RESET, the CNC assumes function G40.
