2) Input item description
B : PROCESS
There are seven processes, namely, the ”ROUGHING”, ”FINISHING”, ”Chamfering”, ”HOLE MA-
CHINING”, ”HOLE (PECK)”, SPIRAL BOTTOM FINISH”, AND ”SPIRAL SIDE FINISH”. The ma-
chining processes that can be specified differ depending on the cutting direction.

U : Cutting direction
Direction in which the tool cuts the pocket of a workpiece on the X–Y plane. The direction is along
the X–axis, the Y–axis, or spiral.
D : D OFS./DIA.
It is the cutter compensation number of the tool to be used. For a hole tool, it is the nominal diameter
of the tool to be used. It is decided automatically using the [F.S.AUTO] soft key.
I : Cutting width/Z point
Width of an effective cutting area of the tool tip. Specify 70% or less of the width of the tool tip.
For a hole tool, it is the deepest point of the tool used. It is decided automatically by pressing the
F.S.AUTO soft key.
J : BOTTOM PITCH/DIAMETER
Input the allowance in the Z direction in one pass during roughing. Input it only for roughing. If it
is not input, cutting is performed in one pass. For hole machining and hole (peck), input the nominal
diameter of the largest tool. When [SPIRAL] is selected as the cutting direction, input the cutter
compensation number of the roughing tool for hole machining and hole (peck). It is decided auto-
matically by using the F.S.AUTO soft key.
K : FINISH PITCH/WIDTH
Input the allowance in the Z direction in one pass during finishing. When FINISHING or [SPIRAL]
is selected, input it only for spiral side machining. If it is not input, cutting is performed in one pass.
Do not input anything for hole machining and hole (peck). When [SPIRAL] is selected, input the
cutting width of the roughing tool for hole machining and hole (peck). It is decided automatically
by using the F.S.AUTO soft key.
NOTE When the cutting direction is changed from [X–AXIS] or [Y–AXIS] to [SPIRAL], or vice versa, be
sure to activate F.S.AUTO because the contents of ”BOTOM PITCH/DIAMETER” and ”FINISH
PITCH/WIDTH” differ.
