Start Angle – Species the angle from angle 0. Angle 0 is a base (horizontal) line from the
center point going right (east) to the circumference. The angle from the base line can be either
posive or negave, up to 90 degrees (or -90 degrees) and rotates the paern either clockwise
or counterclockwise. A negave angle produces a clockwise rotaon; a posive angle produces a
counterclockwise rotaon. For example, to create a hex paern with ats on the top and boom,
enter 0 into the Start Angle DRO. To create a hex paern with ats on the le and right sides, enter
30 (or -30) into the Start Angle DRO.
Diameter – The size of the circular paern as dened by a line through the center point of each hole.
Center X, Center Y – Denes the center point of the circular paern.
Spot Tool # – If this DRO contains a valid tool number when Post To File is clicked, a spot drilling
sequence using this tool number will occur prior to the drilling sequence. The Feedrate, Spindle
RPM, and Z Clear from the drilling sequence will be used for the spot drilling operaon. The depth
of cut for the spot drilling will be taken from the Spot Drill DOC DRO.
Spot Tool DOC – If the drilling operaon includes spot drilling, this DRO will be used to determine
the depth of cut for the spot drilling operaon (for more informaon on dening a tool for a spot
drilling operaon, refer to Spot Tool # earlier in this secon).
6.8.6 Thread Mill Tab
The thread milling roune produces helical tool paths needed for milling straight external or internal
right-handed threads based on pitch, diameter, and length (see Figure 6.34 and Figure 6.35).
