Circle Helix
The circle helix can only be performed with a 3 axes system.
A helix is defined by one of two ways:
 By the radius, depth and pitch
 By the radius, depth and number of revolutions
To program a helix:
 From the PGM screen, press the CIRCLE key to access
the CIRCLE popup Menu.
 Select Helix from the popup Menu.
Entering Data
 In the CENTER field enter the X and Y axes coordinates for the
center of the helix using the ARROW DOWN key to enter the data, and
move to the next field.
 Enter the BEGIN and END depths for Z.
 In the RADIUS field enter the radius.
 For DIRECTION, press either the CW soft key for a clockwise
cutting direction or the CCW soft key for a counter-clockwise cutting
direction.
 In the REVOLUTIONS fields, enter either the pitch (number of
revolutions per Z travel) or the total number of revolutions. The
other field will automatically be filled in.
 The TOOL field will default to the current tool selected.
 In the OFFSET field select INSIDE for a external helix, or OUTSIDE
for an internal helix.
 Enter the Z axis FEED rate. The last feed rate used previously in the
program will be displayed. Select RAPID for a dry run without a tool
by using the Rapid soft key, or select from the drop down menu.
 START ANGLE (optional). Enter the angle where the helix begins
(3 o’clock position is 0 degrees; 12 o’clock position is 90 degrees).
 Press the USE key.
If the tool size and type listed in the TOOL field are incorrect, change
the tool settings before running your program.
