C. High-speed smoothing control
1. Command
The high-speed smoothing control function allows rapid and highly accurate execution of
an EIA/ISO program which is prepared to approximate free-curved surfaces with very
small lines. Compared with the conventional high-speed machining mode, this function
allows machining almost free of cut-surface defects and stripes.
The application of speed control based on a block-to-block angle, such as corner
deceleration, in the conventional high-speed machining mode may cause acceleration and
deceleration to be repeated in too formal a response to minute steps or to errors. As a
result, scratch-like traces or stripes may be left on a cut surface.
By judging the machining shape or contour from the specified continuous lines as well as
from the angle between two blocks, the high-speed smoothing control conducts the
optimum speed control not affected too significantly by very slight steps or undulations.
Consequently, a cut surface with less scratch-like traces or stripes can be obtained.
2. Notes
Give G61.1 (Shape correction ON) before G05P2 to use the high-speed smoothing
control.
In the mode of high-speed machining a block of TtM06 for tool change causes the
execution speed and the fairing function to be lowered and suppressed, respectively,
until a length-offsetting value is made valid for the new tool, which does not occur
implicitly if the length values of the MAZATROL tool data are not to be used in
executing EIA/ISO programs (F93 bit 3 = 0). In this case, therefore, it is necessary to
cancel the high-speed machining mode temporarily so as to give explicitly the required
G43-command for tool length offset.
The high-speed smoothing control is not valid for rotational axes.
See “B. Combination of high-speed smoothing control (G61.1+G05P2) and other
function” in “5-3 Restriction of Combination”.
