Programming
P (a)
Angle at taper of neighboring two tooth is 0~99, unit: degree(°) ,with 2-digit digital. It
is valid after a code value is executed and the value of system parameter No.5143 is
rewritten to a. The value of system parameter
№ 05143 is regarded as angle of
thread tooth. The actual angle of thread in defined by tool ones and so a should be
the same as the tool angle
Q

( dmin)
Minimum cutting travel of thread roughing (radius value without sign symbols). When

dmin, dmin is regarded as the cutting travel of current
roughing, i.e. depth of current thread cutting is (
1 n
−
△ △ △
× d+ dmin) . dmin is
applied because the cutting travel of roughing is undersize and the times of roughing
are excessive, which is caused the cutting travel of thread roughing gradually
△
decreases. After Q( dmin) is executed, the code valu
△
e dmin is value and the
value of system parameter No.5140 is rewritten to minimum cutting travel; when Q
（△
dmin
）
is not input, the system takes No.5140 value as the least cutting value
R (d)
It is the cutting travel of thread finishing, and is the different value(radius value
without sign symbols) of X absolute coordinates between cut-in point Be of thread
finishing and Bf of thread roughing. After R(d) is executed, the code value d is value
and the value of system parameter No.5141 is rewritten to d×1000(unit: 0.001 mm) .
The value of system parameter No.5141 is regarded as the cutting travel of thread
finishing when R(d) is not input
R (i)
It is thread taper and is the different value of X absolute coordinate between thread
start point and end point (unit: mm, radius value). The system defaults i=0(straight
thread) when i is not input
P (k)
It is the depth of thread tooth and is also the total cutting depth of thread( radius
value without sign symbols), and the system alarms when P(k) is not input
Q
△
( d)
It is the first depth of thread cutting (radius value without sign symbols).The system
△
alarms when d is not input
F
Pitch is defined to moving distance ( radius value in X direction) of long axis when
the spindle rotates one rev. Z is long when absolute value of coordinate difference
between C point and D point in Z direction is more than that of X direction ( radius
value, be equal to absolute value of i); and vice versa
J
When the thread run-out is executed, the movement range in the short axis direction
is the same that of G32, must not be less than 0 without direction (the system
automatically confirms the run-out direction according to the initial point of the
program), is modal and its value is specified by radius
K
When the thread run-out is executed, the range in the long axis direction is the same
that of G32, is modal without direction, and the value is specified by radius
