S.Ide
When the tool axis direction command (G53.1) is specified, the "output angle" is
determined form the "computed angle" as follows.
If the parameter PRI(No.19608#5)=0
If the movement ranges of rotary axes are set to the parameters No.19741 -
No.19744, the "output angles" are determined within the ranges.
Tool rotation type or table rotation type machine
<1> The "output angles" are represented by the computed rotary axis angle
pair whose master axis (first rotary axis) moving angle is smaller.
When the master axis moving angle is the same
<2> The "output angles" are represented by the computed rotary axis angle
pair whose slave axis (second rotary axis) moving angle is smaller.
When the slave axis moving angle is the same
<3> The "output angles" are represented by the computed rotary axis angle
pair whose master axis (first rotary axis) angle is nearer to 0 degree
(multiple of 360 degrees).
When the master axis angle is equally near to 0 degree
<4> The "output angles" are represented by the computed rotary axis angle
pair whose slave axis (second rotary axis) angle is nearer to 0 degree
(multiple of 360 degrees).
Mixed type machine
<1> The "output angles" are represented by the computed rotary axis angle
pair whose table (second rotary axis) moving angle is smaller.
When the table moving angle is the same
<2> The "output angles" are represented by the computed rotary axis angle
pair whose tool (first rotary axis) moving angle is smaller.
When the tool moving angle is the same
<3> The "output angles" are represented by the computed rotary axis angle
pair whose table (second rotary axis) angle is nearer to 0 degree
(multiple of 360 degrees).
When the table angle is equally near to 0 degree
<4> The "output angles" are represented by the computed rotary axis angle
pair whose tool (first rotary axis) angle is nearer to 0 degree (multiple
of 360 degrees).
