smoothly blended shapes where the feed rate can remain high through the
blend of one stroke to the next. If there are sharp corners, the control will al-
ways need to slow down or corner rounding will occur.
The affect that blending of strokes can have on feed rate is always to slow
down motion. The programmed feed rate (F) is thus a maximum and the con-
trol will sometimes go slower than that in order to achieve the required accu-
racy.
Too short of a stroke length can result in too many data points. Check how the
CAD/CAM system generates data points to insure that it does not exceed 1000
blocks per second.
Too few data points can result in either “facetting” or blending angles which
are so great that the control must slow down the feed rate. Facetting is where
the desired smooth path is actually made up of short, at, strokes that are not
close enough to the desired smoothness of the path.
High Speed Tooling – The tool holders should be an AT-3 or better with a
nylon back-up screw. The tolerances maintained in the AT-3 design are the
minimum that would be recommended for a high speed process. The nylon
back-up screw increases collet grip on the tool and creates a better seal to aid
in coolant transfer.
Use single angle collet chucks and collets for best grip and concentricity. These
collet systems are made up of a long single angle located in the holder. The
angle per side should be eight degrees or less for best results. Avoid double
angle collet systems when maximum rigidity and close tolerance are dictated.
It is recommended that minimum engagement of 2/3 of the full length of the
bore in the double split single angle collet. However for better results 3/4 to full
engagement is preferred if possible.
High Intensity Lighting - Auxiliary lights provide bright illumination of the work
area. The lights operate automatically when doors open and close, or can be
activated manually using the switch on the side of the control pendant. Turn the
switch on and the lights will turn on when he door is opened and off when the
door is clsed. Set the switch to off and the lights will not turn on when the door
is opened. See setting 238.

The Enhanced Color Remote Jog Handle (RJH) features a color liquid crystal
display (LCD) and controls for increased functionality. It also features a high-
intensity LED ashlight.
