1. MACHINING PROGRAMS FOR
2–AXES (X AND Z AXIS) LATHES
TYPES OF MACHINING
PROGRAMS
251
(1) Roughing process
TOOL–NO. : Management number of a rough machining
tool
CUT–SPD : Cutting speed in rough machining
FEED/REV : Feed amount in rough machining
CUT–DPTH : Depth of cut in rough machining
T–CODE : T code of a rough machining tool
JRotation direction : Spindle rotation direction in rough machining
JPASS POINT 1 X1: X coordinate of pass point 1, traversed by the
tool as it moves from the tool exchange
position to a cutting start point
Z1: Z coordinate of pass point 1, traversed by the
tool as it moves from the tool exchange
position to a cutting start point
JPASS POINT 2 X2: X coordinate of pass point 2, traversed by the
tool as it moves from the tool exchange
position to a cutting start point
Z2: Z coordinate of pass point 2, traversed by the
tool as it moves from the tool exchange
position to a cutting start point
NOTE
2 The position of pass point 2 is automatically determined
from parameter Nos. 9780 and 9781.
JSTART PNT CX: X coordinate of a cutting start point
CZ: Z coordinate of a cutting start point
NOTE
3 When a machining area is specified, a cutting start point is
automatically calculated from blank profile data entered
initially.
JESCAPE AMNT EA: Travel along the X–axis (in outer/inner surface
machining: diameter) or along the Z–axis (in
end facing: radius) for retraction after cutting
Clearance
(1) Standard roughing (2) High speed roughing
