TOMATECH AUTOMATION
without sign symbols), the radius value is equal to X absolute coordinates between cut-in
point Be of
thread finishing and Bf of thread roughing. After R(d) is executed, the specified value d is
reserved
and the system parameter №060 value is rewritten to d×1000(unit: 0.001 mm) . The value
of system
parameter №060 is regarded as the cutting travel of thread finishing when R(d) is not
input;

Ⅰ Programming
R(i): It is thread taper and is the different value of X absolute coordinate between thread
starting
point and end point, rang: -99999.999~99999.999(IS_B）/-9999.9999~9999.9999(IS_C)
(unit:：
mm/inch, radius value). The system defaults R(i)=0(straight thread) when R(i) is not input;
P(k): Depth of thread tooth, the total cutting depth of thread, range: 1～99999999(unit:
least input
increment, radius value, without sign symbols). The system alarms when P(k) is not input;
Q(△d): Depth of the 1st thread cutting, range: 1～99999999 unit: least input increment,
radius
value, without sign symbols). The system alarms when △d is not input;
F: metric thread pitch, its range is referred to Table 1-2;
I: thread teeth per inch for inch thread, its range is referred to Table 1-2.
J：movement amount (run-out amount) (unit: mm/inch, without direction) in the short axis
when
thread run-out; when the short axis is X, its value is designated by radius and is simple
parameter;
K：movement amount (run-out amount) (unit: mm/inch, without direction) in the long axis
when
thread run-out; when the long axis is X, its value is designated by radius and is simple
parameter.
Note: J, K are not compiled in G76, its thread run-out method is the same that of the previous, i.e.
the thread
run-out is executed according to P® or No.19; when J or, K, or J, K are compiled, the thread
run-out
method is the same those of G32, G92.
