Generally, before a T code command, specify the M code to enable
the second geometry tool offset. For details, refer to the manual
supplied by the machine tool builder. The same number as the first
geometry tool offset number is always selected as the second
geometry tool offset number.
During execution, the tool offset value for each axis is either of the
following:
• First geometry tool offset value + tool wear offset value
• First geometry tool offset value + second geometry tool offset
value + tool wear offset value
Example)
• The code is a 4-digit code. (The number of digits of a T code is
specified with parameter No. 3032.)
• The offset type is tool movement (parameter LGT (No. 5002#4)
= 1).
• The lower two digits of the T code is the tool geometry offset
number (parameter No. 5028 = 2).
• Offset is performed when the T code block is executed
(parameter LWM (No. 5002#6) = 0).
• The X axis data for first geometry tool offset number 1 is 1.000.
• The X axis data for second geometry tool offset number 1 is
10.000.
• The tool geometry offset number is specified with the tool
selection number (parameter LGN (No. 5002#1) = 1).
• Signals G2SLC = '1', G2X = '1', and G2Z = G2Y = '0'
If T0102 is specified under the above conditions, the upper two digits
01 of the T code cause the first and second geometry tool offset
numbers 1 to be selected, so that the absolute and machine coordinates
will be 11.000 on the X axis only.
- Offset data
The data for the second geometry tool offset can be set for each path.
The number of items of the data can be set with parameter No. 5024.
The data remains stored even after the power is turned off.
If the data is to be made common to paths, use the memory common
with both 2 path.
