G211 Manual Tool Setting / G212 Auto Tool Setting
T
- Tool number. May be entered as
Tnn or Tnnnn.
H
- Tool tip direction.
H-5 will approach the probe from the X (-) side and H5 from the X (+) side.
*
K
- Indicates a calibration cycle. (Values 1 or 2)
*
M
- Tool breakage tolerance value.
*
C
- Drill diameter value. Only valid with tip directions 5-8. Offset will be adjusted by half this amount (i.e. the
program assumes a 90-degree drill point).
*
X
- Adjust the approach and start points of a probing cycle.
*
Z
- Adjust the approach and start points of a probing cycle.
*
B
- Allows the user to use a different amount to move the tool the tool in X or Z while probing (from the start point
to in position over the probe). Default value is 6mm.
*
U
- Adjust the X start point on
H1 - 4.
*
W
- Adjust the Z start point on
H1 - 4.
*indicates optional
NOTE
The G211 code requires a Tnnn code, either directly before the G211 line, or on the same line. The
G211 code also requires an Hnnn code. The G212 code only requires an Hnnn code on the same line
but a Tnnn code tool call is required prior.
Using G211 Manual Tool Setting
IMPORTANT
The Automatic Tool Probe must be calibrated before using G211 / G212 .
The
G211 code is used to set an initial tool offset (X, Z or both). To use the probe arm must be lowered. Then the tool
tip jogged into place about 0.25 in from the corner of the problem that corresponds to the desired tip direction. The
code will either use the current tool offset if one has been called previously or the tool offset may be chosen using a
T
code. The cycle will probe the tool, enter the offset and return the tool to the start position.
Using G212 Auto Tool Setting
The
G212 code is used to re-probe a tool that already has an offset set, such after an insert is changed. It can be also
be used to check for tool breakage. The tool will be moved from any location into proper orientation to the probe by
the
G212 command. This path is determined by the tool tip direction variable H, this variable must be correct or the
tool may crash.
IMPORTANT
Care must be used for touching off any back working tools, to keep from hitting the spindle or
the back wall of the machine. A tool and offset must be called
Tnnn
before running G212 , or
an alarm will be generated.
G212 code is used to re-probe a tool that already has an offset set, such after an insert is changed. It can be also be
