G133
Command function: the tool executes the linear cutting cycle from starting at the specified parameter data
till the programmed rectangular convex plane is machined completed.
Command explanation: related commands are referred to Table 3-2.
G132
：
outer rectangle roughing CCW
G133
：
outer rectangle roughing CW
XY
：
start-up coordinates in XY plane
I
：
X-axis width of outer rectangle roughing(it is more than 0, and its absolute value is done when it is
negative
）
J
：
Y-axis width of outer rectangle roughing
（
it is more than 0, and its absolute value is done when it is
negative
）
A: X-axis width of blank
（
it is more than 0, and its absolute value is done when it is negative
）
B
：
Y-axis width of blank
（
it is more than 0, and its absolute value is done when it is negative
）
E
：
Allowance in XY plane of outer rectangle roughing
（
it is more than 0, and its absolute value is done
when it is negative. The value set by No.5124 is defaulted when it is not specified ）
W
：
Z-axis depth of first cutting is the distance downward from R reference plane, and should be more
than 0, its absolute value is done when it is negative (when the first cutting depth exceeds groove bottom
position, directly machining the groove position is done
）
Q ： Z-axis cutting depth increment every time. its absolute value is done when it is negative
K
：
Cutting width increment in XY plane
（
it should be less than tool diameter, its absolute value is done
when it is negative; when K is not specified, K is defaulted to tool radius D
