The total length is the distance from the spindle head center of rotation to the
tip of the tool. It can be calculated by adding the gauge length and pivot length.
This number is entered into the CAD/CAM program, which will use the value
for its calculations.
Offsets
The work-offset display is found on the offset display by pushing the Page Up
button. The G54 through G59 or G110 through G129 offsets can be set by
using the Part Zero Set button. Position the axes to the work zero point of the
workpiece. Using the cursor, select the proper axis and work number. Press
the Part Zero Set button and the current machine position will be automatically
stored in that address. This will work with only the work zero offsets display se -
lected. Note that entering a nonzero Z work offset will interfere with the opera -
tion of an automatically entered tool length offset.
Work coordinate numbers are usually entered as positive numbers. Work
coordinates are entered into the table as a number only. To enter an X value of
X2.00 into G54, cursor to the X column and enter 2.0.
Five-axis Programming Notes
Use a tight synchronization cut across resolution of geometry in the CAD/CAM
system will allow smooth flowing contours and a more accurate part.
Positioning the machine to an approach vector should only be done at a safe
distance above or to the side of the workpiece. When in the rapid mode, the
axes will arrive at the programmed position at different times; the axis with
shortest distance from target will arrive first, and longest distance last. A high
feed rate will force the axes to arrive at the commanded position at the same
time avoiding the possibility of a crash.
G Codes
Fifth-axis programming is not affected by the selection of inch (G20) or metric
(G21), as A and B axes are always programmed in degrees.
G93 inverse time must be in effect for simultaneous 5-axis motion. In G93
mode, the maximum feed rate will include the combination of all axis motion
in one block of code. The limit is set by the control and looks at encoder steps
programmed for all axes in a block of code.
Limit the post processor (CAD/CAM software) if possible; the maximum speed
in G93 mode is 32 degrees per minute. This will result in smoother motion,
which may be necessary when fanning around tilted walls.
M Codes
Important! It is highly recommended that the A/B brakes be engaged
when doing any non 5-axis motion. Cutting with the brakes off can cause
excessive wear in the gear sets.
