Position/Milling
MILLPWRG2 offers several Position / Milling functions that let you 
program a Line, Arc, Blend (Arc), Blend (Chamfer), and Contour that 
can be accessed directly using the Position/Milling soft key popup 
menu.
Position / Drill
The Position / Drill function will move the table to specific position  
based upon the X and Y axes coordinates entered.

Arc
An arc can be defined several ways:
With a From point, To point and a radius
With a From point, To point and a center point
With a From, To and a 3rd point along the arc
With a start point to an end point for a sweep angle
Choose a method based upon the information available from part 
drawing. While programming, keep in mind that the arcs sweep angle 
is measured from the X axis.

Chamfer
A Chamfer is done in the same way, but with less steps.  In the Size 
field enter the length of the chamfer.
A chamfer is a bevel or line that’s inserted between two lines to 
relieve sharp angles or corners on a part. A chamfer can be inserted 
between two intersecting lines whose steps are adjacent in the 
program step.
A chamfer can also close a contour (e.g., a triangle) by inserting the 
chamfer step immediately after the last step in the...

Contour
The Contour step enables you to approach and/or depart from your 
part on a straight line or with an arc.
The contour step must immediately follow the contour steps.
Contours can only be associated with lines, arcs, blends and 
chamfers. By adding contours before and/or after a continuous tool 
path, youll avoid starts and stops striking against the workpiece 
edge.
With an arc approach/departure, the tool will take a rounded turn as it 
nears or...

Tool path description:
The tool path follows the profile of the contour steps.  
The Z step size is determined by the system and will not exceed the 
specified distance or number of passes.  
The tool retracts to the active datums retract position between Z 
passes. 
Approach and departure moves are optional.  For Line, the tool 
approaches/departs with a linear move tangent to the first or last 
step of the contour.  
For Arc, the tool...

Rectangular milling functions
MILLPWRG2 offers several rectangular milling functions that let you 
program pockets, frames, faces and slots. For 2 axes systems, Refer 
to Chapter 1, Operating in 2 Axes and 3 Axes Modes on page 31.
Rectangle pocket
A pocket is a cavity or area on the part where material is removed 
when you machine. You can program a rectangular pocket three ways:
Using the coordinates of two diagonal corners.
Using the coordinates of one...
