Angle of rotation axis
When tool axis direction control (G53.1) has been performed, more than two pairs of
"computed angles" of the rotation axes usually exist.
The "computed angle" is the candidate angle at which the rotation axis is to be
controlled in the tool axis direction specified by G53.1.
The "output angle" is determined from the "computed angle" based on the "output
judgement conditions" described below.
"Output judgement conditions"
Tool rotation type or table rotation type machine
<1> When master axis (first rotation axis) moving angle of a pair is
smaller than those of other pairs, the pair of computed angles whose
master axis moving angle is smallest is the pair of output angles.
↓
↓ When the master axis moving angles of pairs are the same
↓
<2> When slaver axis (second rotation axis) moving angle of a pair is
smaller than those of other pairs, the pair of computed angles whose
slave axis moving angle is smallest is the pair of output angles.
↓
↓ When the slave axis moving angle of pairs are the same
↓
<3> When master axis (first rotation axis) angle of a pair is nearer to 0
degree (multiple of 360 degrees) than other pairs, the pair of
computed angles whose master axis angle is nearest to 0 is the pair
of output angles.
↓
↓ When the master axis angles of pairs are equally near to 0
↓ degree
<4> The pair of computed angles whose slave axis angle is nearest to 0
degree (multiple of 360 degrees) is the pair of output angles.
Mixed type machine
<1> When table (second rotation axis) moving angle of a pair is smaller
than those of other pairs, the pair of computed angles whose table
axis moving angle is smallest is the pair of output angles.
↓
↓ When the table moving angle of pairs are the same
↓
<2> When tool (first rotation axis) moving angle of a pair is smaller than
those of other pairs, the pair of computed angles whose tool axis
moving angle is smallest is the pair of output angles.
↓
↓ When the tool moving angle of pairs are the same
↓
<3> When table (second rotation axis) angle of a pair is nearer to 0
degree (multiple of 360 degrees) than those of other pairs, the pair of
computed angles whose table angle is nearest to 0 degree is the pair
of output angles.
↓
↓ When table angles of pairs are equally near to 0 degree
↓
<4> The pair of computed angles whose tool (first rotation axis) angle is
nearest to 0 degree(multiple of 360 degrees) is the pair of output
angles.
