Making a decision on the basis of the spacing between adjacent programmed points, Making a decision at a corner
Only three basic axes (or their parallel axes) are related to “the programmed
block length” in “Conditions to enable Nano smoothing” of explanation for Nano
smoothing, and two rotary axes have no relation to it. In the same way, only
three basic axes (or their parallel axes) are related to “Making a decision on the
basis of the spacing between adjacent programmed points” and “Making a
decition at a corner”, and two rotary axes have no relation to them. However, in
the block that Nano smoothing mode is canceled according to these conditions,
Nano smoothing for rotary axes is also canceled.
Other explanation is same as the conventional Nano smoothing.
Restrictions
Nano smoothing for 5-axis machining can be used together with Tool center point
control for 5-axis machining (type I: G43.4). However PS5421 alarm (ILLEGAL
COMMAND IN G43.4/G43.5) occurs if Nano smoothing for 5-axis machining is
used with Tool center point control for 5-axis machinig (type II: G43.5) or Tool
posture control of Tool center point control for 5-axis machining.
Other restrictions are same as the conventional Nano smoothing.
Parameters
19587 Tolerance of rotary axes for nano smoothing for 5-axis machining
[Input type] Setting input
[Data type] Real axis
[Unit of data] degree (input unit)
[Minimum unit of data] Depend on the increment system of the applied axis
[Valid data range] 0 or positive 9 digit of minimum unit of data (refer to the standard
parameter setting table (B))
(When the increment system is IS-B, 0.0 - +999999.999)
Tolerances of rotary axes for nano smoothing for 5-axis machining are specified.
Only values for rotary axes that are commanded in nano smoothing for 5-axis
machining are valid.
The minimum increment is applied as tolerance if this parameter is 0.
Other parameters are same as the conventional Nano smoothing.
