TABLE TO PROGRAM
This is the distance from the tabletop to where you are holding size in X Y.
When taper cutting (G51 / G52)
Here are four possible situations when the workpiece is mounted directly on the table.
1) Cutting with the top of the die UP and you want a die land, this value will be the
thickness of the part MINUS the die land.
2) If cutting with the top of the die UP and you do NOT want a die land, this value will
be the thickness of the part.
3) If cutting with the top of the die DOWN and you want a die land, this value will be the
die land amount.
4) If cutting with the top of the die DOWN and you do NOT want a die land, this value
will be zero.
When 4-Axis cutting (G74)
When 4 axis cutting (G74 or G141) this is the amount that the bottom of the part is above
the worktable. In this case a fixture would be lifting the part from the worktable.
TABLE TO NEXT
This parameter sets the opposite side of the part from T-Program, in respect to the
worktable.
When taper cutting (G51 / G52)
When taper cutting, Table to Next will be zero if the die land is up. If the die land is
down (T-Program = 0) then T-Next is the workpiece thickness.
When 4-Axis cutting (G74)
This value represents the distance from the table to the 2
nd
plane when you have a 4 axis
(independent UV) program. When the part is on the table, Table to Program is usually 0
(1
st
plane) and Table to Next will usually be the workpiece thickness (2
nd
plane).
Note: When 4 axis cutting, it must be used. This sets the position of the u-v axis plane in
your part, so set this value to the amount that the top of the part is above the table.
