TRAK LPM Programming, Safety, & Operating Manual

LINE ANGLE: is the angle of this mill line (moving from begin to end) measured

counterclockwise from the positive X axis (that is 3 o’clock)

GUESS: This softkey will appear when the prompt is on X or Y dimensioned data. Press

the Guess key before you press INC SET or ABS SET to enter the data as a guess. See

Section 9.7 for using Guess and Section 9.8 for using the Graphics to enter a Guess.

9.3 A.G.E. Arc Prompts

Press the A.G.E. ARC key.

Prompts in A.G.E. Arc programming:

TANGENT: this refers to the tangency of the mill to the previous event. See Section

9.11 for a discussion of tangency.

DIRECTION: is the clockwise (input 1), or counterclockwise (input 2) direction of the

arc

X END: is the X dimension to the end of the arc cut; incremental is from X Begin

Y END: is the Y dimension to the end of the arc cut; incremental is from Y Begin

X CENTER: is the X dimension to the center of the arc; incremental is from X End

Y CENTER: is the Y dimension to the center of the arc; incremental is from Y End

CONRAD: is the dimension of a tangential radius to the next event

RADIUS: is the radius of the arc

CHORD LENGTH: is the straight line distance from the begin point to the end point

CHORD ANGLE: is the angle spanned by the arc

In addition to the normal Softkeys, this additional one will appear in A.G.E. Arc

programming:

GUESS: this softkey will appear when the prompt is on X or Y dimensioned data. Press

the Guess key before you press INC SET or ABS SET to enter the data as a guess. See

Section 9.7

9.4 Skipping Over Prompts

In the A.G.E., events don't have to be fully defined before you can go to the next one.

You can skip the data you don’t know by using the cursor hard keys on the Program

Panel. After you press the arrow down key at the last prompt, the event will move to the

left side of the screen and the Select Event screen will appear.

When skipping over prompts or editing, always use the cursor keys. Using INC SET or

ABS SET will change the data.

If you want the event back on the right side, use the left hard key.

9.5 The OK/NOT OK Flag

Each A.G.E. event has a flag that tells you if it has been fully defined. Sometimes data

from later events is needed to define previous events. To the immediate right of the event
