A = 180 – A’
Note 1 ： The code for directly inputting graphic dimension is valid in only Auto mode, and an alarm occurs in
MDI, DNC mode.
Note 2
：
The following G codes cannot be used in the blocks which are the same those of directly inputting
graphic dimension, also in the blocks which define continuous graph’s directly inputting graphic
dimension, as well as in the blocks which the directly inputting graphic dimension is executed in their
mode.
G codes in group 00
（
except for G04
）
G codes except for G00, G01, G32 in group 01
G codes in group 10
（
fixed cycle for drilling
）
G codes in group 16
（
plane selection
）
G22, G23
Note 3 ： Cannot insert the chamfering C or corning R code in thread cutting blocks.
Note 4
：
In single block run, when the system uses the code for directly inputting continuous graphic
dimension, and the next block determines the previous block’s end point, the machine does not stop
at the end point of the previous block in single block stop mode rather than in feed hold mode.
Note 5
：
In the following programs, angle tolerance of counting intersection point is ±1 degree.
（
the counted
movement value is too big at intersection point.
）
X_,A_;
（
an alarm occurs when the angle code A is specified to 0 degree or within
180±1
degree.
）
Z_,A_;(an alarm occurs when the angle code A is specified to 90 degree or within
270±1
degree. ）
Note 6
：
When the intersection point is counted and angle difference between two lines is within
±1
degree, an
alarm occurs.
Note 7: The chamfering or corning R is ignored when angle difference of two lines is within ±1.
Note 8 ： The system must specify a coordinate code value (absolute code value) and an angle code value in a
block which follows the block only having specified an angle code.
（
Example
）
N1 X_ ,A_ ,R_;
N2 ,A_;
N3 X_ Z_ ,A_;
(Besides the coordinate code value, must specify an angle code in N3, otherwise, an alarm occurs.
Besides, the coordinate code value must not be an absolute code, otherwise, an alarm occurs. ）
Note 9
：
In tool nose radius compensation, blocks of the angle code for directly inputting graphic dimension
have no movement blocks.
Note 10 ： In continuous graphic dimension directly input codes, when there are 2 or more movement blocks
between codes, an alarm occurs.
Note 11
：
When CCR(No.3405#4) is set to “1”
，
the block address A of G76
（
multiple thread cutting cycle
）
is the
tool nose angle code. Besides, when A or C is an axis name, A and C cannot be used in the angle
codes and chamfering codes of graphic dimension directly input. Please use ,A_ and ,C_
