Set the reference angles of the rotation axes used to execute tool radius
compensation for 5-axis machining.
Set the angles of the rotation axes assumed when the tool direction (parameters
No.19622 to 19623).
Usually, set a value of 0.0.
19622 Reference angle of tool axis of plane of liner axes 2 and 3 (RA)
19623 Reference angle of tool axis of plane of liner axes 3 and 1 (RB)

increment system IS-B IS-C Unit
Data unit 0.001 0.0001 deg
[Valid data range] -99999999 - +99999999
Set the two angles RA and RB to specify the direction of the tool axis used to
execute the tool radius compensation for 5-axis machining.
Parameters No.19622 and 19623
As the directions of compensation vectors, using the direction of linear axis 3
(parameter No.19613) as a reference, set the rotation angles (R
A
and R
B
) from
that reference.
R
A
: Rotation in the plus direction is rotation from the plus direction of linear
axis 2 to the plus direction of linear axis 3, assuming that the rotation is on
the plane of linear axes 2 and 3.
R
B
: Rotation in the plus direction is rotation from the plus direction of linear
axis 3 to the plus direction of linear axis 1, assuming that the rotation is on
the plane of linear axes 3 and 1.
Linear axes 1, 2, and 3 are those axes that have been specified with parameters
No.19611 to 19613.
Linear axis 2
Linear axis 1
Linear axis 3
If the tool axis is in the direction of linear axis 3
R
