Command specifications:
G32 is modal;
IP_
End point coordinate value. It can be specified by the absolute command value or
incremental command value. The system specifies the different IP_ value to execute
the straight thread cutting, end face thread cutting and taper thread cutting.
F
Metric pitch is moving distance of long axis when the spindle rotates one-turn and its
value range is referred to the following table. After F is executed, it is valid until F with
specified pitch is executed again. The pitch F value precision is the last two-digit of
the decimal.
J
Travel in the short axis in thread run-out with positive/negative sign symbols and the
value range is referred to the following table; the value is specified by the radius
value.
K
Length in the long axis in thread run-out. The value range is referred to the following
table. It has no direction.
Q
Initial angle between spindle rotation one-turn and starting point of thread cutting.
The value range without the decimal is referred to the following table. Q is non-modal
parameter, must be defined every time, it is 0
0
.when it is not specified, the system
specifies Q different value can cut multi-thread.
Q rules:
1. Its initial angle is 0° if Q is not specified;
2. For continuous thread cutting, Q specified by its following thread cutting block except for
the first block is invalid, namely Q is omitted even if it is specified;
3. In ISB mode, Q unit is 0.001°. ISC mode, Q unit is 0.0001°. Example, in ISB mode,
Q180000 is input in program if it offsets 180° with spindle one rev; if Q180 or Q180.0, it is
0.18°. When the system specifies the value more than 360000, it counts based on
360000(180).
4. It is suggested that the system should use G97 instead of the constant surface cutting
speed control in thread cutting.
