77
Canned cycle B (G73,
G74, G76,
G80～G89)
It is possible to perform 12 canned cycles including deep drilling
cycle, finish boring cycle, tapping cycle and reverse-tapping cycle.
78
Inch/metric conversion
(G20, G21)
Input in Inch or metric system can be selected by switching G
codes.
G20: Input in inch input
G21: Metric input
79
Circular interpolation
(G02, G03)
Using G02 (or G03) may achieve any circular interpolation within
0～360° with the feedrate of F code command .
G02: Clockwise (CW)
G03: Counterclockwise (CCW)
80
Feedrate sine-curve
control
When an axis in the arc plane does not move (the axis is
considered as an imaginary axis) in the sine curve interpolation
command , the other 2 axes may be used for sine-curve
interpolation.
81
Circular interpolation by
radius designation
In circular interpolation, directly specifying radius with radius value
R rather than I, J and K simplifies programming. An arc over or
below 180° can be instructed.
82
External deceleration
The mechanical vibration at the end of stroke can be minimized and
the range of effective stroke maximized through the function.
External deceleration is not applicable for an additional axis.
83
External workpiece
number search A
The function is used to input any program number among 1～31 for
NC from the outside such as machine side and to select these
programs from the memory of NC.
84
External data input
The function is used to transmit the following data from the outside
such as machine side:
(1) External workpiece number search C;
(2) External cutter compensation C;
(3) External alarm message;
(4) External operation information.
85
Automatic acceleration/
deceleration for feed
Cutting feed and manual continuous feed can be set by parameters
to make power type acceleration/ deceleration in 8ms～4000ms
time constant.
Additional optional block
skip
9 switches for skipping over selected blocks can be set on machine
side by adding a digit (1~9) after the switching command ”/” of a
block. When a switch n for skipping over selected blocks is enabled,
the blocks with “/n” will be skipped over.
