Programming the lower vertical Line
Next, the line that starts vertical from the bottom line at the end of the 
arc will be entered.
Press the LINE key.
Again, MILLPWR
G2 assumes that the program is continuing from the 
last step. So it has automatically filled in the From: X1, and Y1 fields, 
the Z: fields, Tool fields, Feed: fields, and the Offset field.
Using the numerical keypad, enter the following information:
In the To: X2 field enter -3.0, and ARROW DOWN.
In the To: Y2 field enter -.838, and ARROW DOWN.
Press the USE key.
Next, the lower angled line will be added.

Programming the lower angle Line
Next, the line that angles in to the part from the lower vertical line will 
be added.
Press the LINE key.
MILLPWR
G2 has again assumed that it will continue from where it left 
off, and all fields are filled in except for the To: fields. The cursor is also 
located here, in the first field.
Using the numerical keypad, enter the following information:
In the To: X2 field enter .75.
Now press the ABS/INCR key.
The INC field next to the X2 field has opened. Press the X1 soft key. 
X1 is displayed in this field next to the X2 field.
ARROW DOWN once to the Y2 field.
In the To: Y2 field enter 0.00. 
Press the USE key.
Next, the upper angle line will be added to the program.
If the X1 soft key had not been pressed, then INC would 
not have been used, and MILLPWRG2 would assume that 
ABS is to be continued.

Programming the upper angle Line
The upper line that angles away from the part will now be added.
Press the LINE key.
With MILLPWR
G2 assuming that it is continuing from where it was left 
off, all fields are filled in except for the To: fields. Which is also where 
the cursor is located in the first To: field.
Using the numerical keypad, enter the following information:
In the To: X2 field enter -3.0, and ARROW DOWN.
In the To: Y2 field enter .838.
Press the USE key.
Although changes are not lost if a power cycle occurs, you may wish 
to save your program periodically while creating it, or you may want to 
discard the most recent changes made since the last save.
Press the Save / Discard soft key.
Select  Save from the popup menu to save the program, or select 
discard to delete the most recent changes since the last save.
Next, a blend will be added to the two angled lines.

Programming a blend
In this step, a BLEND will be inserted between program steps 6 and 7.
ARROW UP one step to highlight program step 7.
Press the BLEND key.
In the Type field be sure that Blend is selected.
Program Step 7 has now moved to program Step 8, and the Blend 
program step is now Step 7.
Also notice that the continuous line in the program steps between 
steps 6 and 8 is now broken.  This indicates that these steps will be 
blended.
ARROW DOWN to the Radius: field, and enter .25.
Leave the Contour field set at the default setting of Open.
Press the USE key.
The two angled lines are now blended with a .25 radius, and the line 
in the programming steps is now continuous from Step 2 through 
Step 8.
Press the down ARROW key to Step 9 (last step in the program) to 
continue with the program.
The following step will close the contour of the part.
The blend step could have been added prior to adding the 
next line in the program step, but it would not have been 
displayed until the connecting line was added.

Closing the contour
The contour of the part will now be closed, and all milling steps 
entered will be one continuous machining operation.
Press the LINE key.
As MILLPWR
G2 assumes that you are continuing from where it was 
left off, all fields are filled in except for the To: fields. Which is also 
where the cursor is located in the first To: field.
Using the numerical keypad, enter the following information:
In the To: X2 field enter -3.0, and ARROW DOWN.
In the To: Y2 field enter 1.5.
Press the USE key.
The contour of the part is now complete.  You may notice that the tool 
path shows a double radius where the tool started, and then ended.  
This is because the program is dimensioning the center of the tool.
The continuous line along the program steps has now 
changed to a closed rectangle.  This represents that the 
contour is now closed.  This happens when the To point of 
the last step is the same as the From point of the first step.

A popup menu will appear for selecting the type of hole pattern to be 
used.
Select the Bolt Circle selection. The Bolt Circle input dialogue will be 
displayed.
In the Center  X field enter 0.00, and Y field enter 0.00. For this 
program it is also the Center location for the Bolt Circle (which is also 
where datum X 0 and Y0 was set).
ARROW DOWN to highlight the Z: End field, and press the CLEAR key to 
delete the default data in the field that may be present.
Enter a value of -.40 in the Z: End field.

(Clockwise) soft key.
ARROW DOWN to highlight the Holes field, and enter 5.
Press the USE key.
In this example, the starting and ending angles were not changed. As 
a result, the first hole is placed at zero degrees. If you were to look at 
the face of a clock, zero degrees will be at 3 o’clock. Without a 
specified ending angle MILLPWR
G2 spaces the number of holes 
entered evenly around a full circle. If a counter-clockwise direction 
was applied to the hole pattern, the second hole of our five hole 
pattern will be between 12 o’clock and 1 o’clock. The holes continue 
around the circle as shown below.

Testing the program
Whenever a new program has been created, it should always be 
tested first.
Run Options
Two options are available: Dry Run will move the table and Quill but no 
material will be cut, and Single Step will run the program one step at 
a time, then pause until GO is pressed to proceed with the next step.
Press the Run Options soft key.
Press the selected option to run the program.
Dry run with table movement
The complete program will be run, and the cutting of the part will be 
displayed graphically as the program steps are being performed.
The following steps will run the program graphically, and the table will 
move.
Press the Run Options soft key.
Press the Dry Run soft key.
Highlight step 001 of the program.
Press the Exit soft key.
Press the GO soft key (the table will move).
Before you press the GO key to begin the dry run, ensure 
that the tool will not touch the workpiece when the quill 
begins to move. To avoid tool interference, do one or more 
of the following:
- Lower the knee
- Remove the tool or workpiece
- Reestablish datum away from the part
