Pitch Specifications
The pitch is the travel distance of the traverse axis per 360-degree rotation of
the rotating axis. The travel distance of the rotating axis per layer can be cal-
culated from the winding width and pitch. The unit for the pitch is the same as
that for the traverse axis (Y or U) and it is valid to four decimal places.
Travel distance of rotating axis per layer = |Winding width| ÷ pitch × 360
An error (overflow error) will occur if the pitch is set to 0. The upper limit of the
winding width is 745654.
Example:
Assume there are 100 rotations per layer and a winding width 40 mm.
X axis unit: degrees, Y axis unit: mm
• Specifying the Windings of the Rotating Axis per Layer
G32 X36000 Y40
360 degrees times 100 rotations
• Specifying the Pitch
G32 X0.4 Y40
If the pitch is 0.4, then, |40| ÷ 0.4 × 360 = 36000
Start Specification (A1991/A1993)
A start specification can be made. An error will occur (number out of range) if
a non-specified value is set.
0 to 3999 9999 Decimal can be placed anywhere as long as there are no more than 4 decimal places.
Start Specification
If a start specification is made, the traverse axis will stop at the start of linked
G32 operation and the rotating axis will turn for the amount set for the start
specification before starting the traverse axis. (This occurs only before the first
linked block, not before all linked blocks.) The unit for the start specification is
the same as that for the rotating axis (X/Z). If a negative travel distance is
specified, an error will occur (negative rotation specification error) and if 0
travel is specified, operation will be the same as if the start specification had
not been made.
The travel distance for the start specification must be included in the number
of X-axis or Z-axis rotations explained in Restrictions under 7-3-15 G32:
TRAVERSE .
Operation is performed according to the settings. A comparison of operation
to the normal traverse operation in Pass Mode is given in the following table.
Normal traverse operation
in Pass Mode (for reference)
Can be changed for each
block.
Overrides are valid.
Can be output from each
block.
Specified as windings (rota-
tions) per layer.
Can be changed for each
block.
Linked traverse (customized function)
Operates according to the first linked block with
G32.
Overrides are valid.
Operates according to the first linked block with
G32
Can be specified as windings (rotations) per
layer or as the pitch.
Same.
