When selecting startup machining mode, set a desired number from 201
to 205 in the startup selection item on the machining data group screen
of the machining condition setting screen in the same way as in edge
machining mode selection. At this time, the same number can be set for
both edge machining and startup machining. Moreover, only startup
machining mode can be selected without selecting edge machining mode.
When startup machining mode need not be selected, set 0.
For startup machining, the machining conditions set on the edge
machining condition setting screen are used, However, the data required
for startup machining consists only of a return feedrate, return distance,
return power, return frequency, and return duty cycle; the other setting
data does not affect the startup machining.
In startup machining mode also, conventional commands (such as S, P,
Q, and F) can be used with a machining program.
S To use this function, the optional machining condition setting function
is required.
S This function cannot be used with the single block function or dry run
function.
S This function can be used together only with X–Y plane facing.
It cannot be used together with any other function (such as cylindrical
interpolation, normal–direction control, or three–dimensional
cutting).
S When this function is used, automatic corner override cannot be used.
S This function and automatic corner deceleration cannot be used at the
same time.
(1)After assist gas specification using G32, piercing is performed with
G24.
(2)Upon the completion of piercing, the assist gas is switched to that used
for machining, and cutting is started.
(3)At this time, in section A (set return distance), machining is performed
according to the feedrate, power, frequency, and duty cycle set for
startup machining.
(4)After machining is performed for the return distance, the normal
feedrate and beam output condition are resumed as in the case of edge
machining.
