Path traversing behavior
9.1 Tangential control (TANG, TANGON, TANGOF, TANGDEL)
Programming
TANG (Faxis,Laxis1,Laxis2,Coupling,CS,Opt)
or
TANGON (Faxis,Angle, Dist, Angletol)
or
TANGOF (Faxis)
or
TLIFT (Faxis)
or
TANGDEL (FAxis)
Simplified programming:
A coupling factor of 1 does not have to be programmed explicitly.
TANG(C, X, Y, 1, "B", "P") can be abbreviated to TANG(C, X, Y, , , "P"). As
before, TANG(C, X, Y, 1, "B", "S") can be written as TANG(C, X, Y).
The TLIFT(...) statement must be programmed immediately after the axis assignment with
TANG(...). Example:
TANG(C, X, Y...)
TLIFT(C)
Deactivate TLIFT
Repeat axis assignment TANG(...) without following it by TLIFT(...).
