D : Tool small diameter
The small diameter of chamfer tool.
J : Chamfer angle
The tool nose angle of a chamfering tool.
H : Tool out depth
The thrust depth of a chamfering tool.
F : The feed rate of the tool.
E : Z_cut feed rate
The cutting feed rate in Zaxis direction from point R.
(Point R = End point Z + Bottom removal + Clearance)
C : Cutting width
The machining allowance of one pass in the XY direction.
It is specified a rate (%) of the tool. (less than 70%)
X : Center point X
X coordinate of the center of the circle.
Y : Center point Y
Y coordinate of the center of the circle.
R : Radius
The radius of a circle.
S : Cycle select
Select the drilling cycle for pre-hole
1: G81 (Normal drilling)
2: G83 (Peck drilling)
3: G73 (High-speed peck drilling)
Q : Pitch depth
The depth of cut for each cutting cycle.
It is used for G83 (S:2) and G73 (S:3).
M : Clearance
The amount of clearance for cutting feed in the Z axis at the approach or escape
movement. The default data is 3mm.
W : Cutting direction
1: Down-cut : Rotation of the cutting tool in the forward direction
2: Up-cut : Rotation of the cutting tool in the reverse direction
