B-63324EN/03 PROGRAMMING 14.COMPENSATION FUNCTION
- 455 -
- Specifying I, J, and K
Addresses I, J, and K must all be specified to start three-dimensional
tool compensation. When even one of the three addresses is omitted,
two-dimensional cutter compensation C is activated. When a block
specified in three-dimensional tool compensation mode contains none
of addresses I, J, and K, the same vector as the vector generated in the
previous block is generated at the end of the block.
- Modal I, J, and K commands
When bit 0 (OKI) of parameter No. 6030 is set to 1, three-dimensional
tool compensation can be performed even if one or two of the I, J, and
K commands are omitted; the omitted addresses are assumed to be the
same as the previous values.
Example
N1 G41 X_ Y_ Z_ I_ J_ K_ D_
N2 X_ Y_ Z_ I_ K_ Vector calculation is
performed with the omitted J
value assumed to be the
value in N1.
N3 X_ Y_ Z_ I_ Vector calculation is
performed with the omitted J
and K value assumed to be
the values in N1 and N2,
respectively.
EAccurate vector command
When bit 0 (ONI) of parameter No. 6029 is set to 1, up to nine
significant digits (nine digits in the integer part to nine digits in the
decimal part) can be specified in the I, J, and K commands of three-
dimensional tool compensation, regardless of the increment system of
the reference axis.
