8.6 POCKET Events
This event selection gives you a choice between, circle pocket, rectangular pocket and
irregular pocket within the XY plane.
Pockets include machining the circumference, as well as all the material inside the
circumference of the programmed shape. If a finished cut is programmed, it will be made
at the completion of the final pass. The cutter will arc in and arc out of the finish cut and
position itself the finish cut dimension away from the part before moving the tool out of
the part.
The factory setting for tool step over while machining a pocket is 70%. This may be
changed. When you first enter the pocket event, the blue ? will appear next to the help
key. Pressing Help will give you the choice of entering a new tool step over percentage.
The value you enter here will remain the same until you change it again.
8.6.1 Circular Pocket
Press the CIRCLE PCKT soft key if you wish to mill a circular pocket.
Prompts for the Circle Pocket:
X Center: is the X dimension to the center of the circle
Y Center: is the Y dimension to the center of the circle
Z Rapid: is the Z dimension to transition from rapid to feed
Z End: is the Z dimension at the bottom of the pocket; incremental is from the previous
event
Radius: is the finish radius of the circle
Direction: is the clockwise (input 1), or counterclockwise (input 2) direction for milling
# Passes: number of cycles to machine to the final depth spaced equally from Z Rapid to
Z End (hint: keep Z Rapid small)
Entry mode: choose between a zigzag ramp and a plunge. The plunge will machine
straight down Z to the appropriate Z depth. The zigzag ramp will move in a zigzag
pattern to depth. See Section 8.6.5 for more information about the zigzag ramp.
Fin Cut: is the width of the finish cut. If 0 is input, there will be no finish cut. See
Section 8.6.7 for a bottom finish cut.
RPM: is the spindle RPM for the event. INC SET will use the RPM of the previous
event.
FIN RPM: is the spindle RPM for the finish cut.
Z Feedrate: is the Z feedrate from Z rapid to Z end in in/min from .1 to 700, or mm/min
from 5 to 17780
XYZ Feedrate: is the milling feedrate in in/min from .1 to 800, or mm/min from 5 to
20320
Fin Feedrate: is the milling feedrate for the finish cut
Tool #: is the tool number you assign
8.6.2 Rectangular Pocket
Press RECTANGLE soft key if you wish to mill a rectangular pocket (all corners are 90
o
right angles and the sides are parallel to the X and Y axes).
