Rectangle frame
When you program a rectangular frame, you define it by its first corner, 
and its size or diagonal corner. You can program a frame in one of 
three ways:
Using the coordinates of two diagonal corners.
Using the coordinates of one corner and the size of the frame.
Using the coordinates of the center and the size of the frame.
To program a rectangular frame:
From the PGM screen, press the RECT key to access the RECT popup 
Menu.

Rectangle face
The “Rectangle Face” step provides a quick way to face off your 
workpiece. Simply enter the coordinates from one corner and either 
the size of the area to be faced off or the coordinates for a diagonal 
corner. MILLPWR
G2 will position your table at the lower left end of the 
area youve programmed.

Tool path description:
Machining of the face begins near the first corner.
The tool plunges at the Z feed rate.
The tool makes back and forth passes in the XY plane along the 
defined length of the face.  Tool motion extends beyond the ends of 
the rectangle by an amount equal to the tool radius.
The XY step size is determined by the system and will not exceed 
the specified percentage of the tool diameter.
The Z step size is determined by the...
