Tormach Tooling System

<< < (2/2)

Will_D:
Well its been a while but I am starting to investigate tool changing on my Sieg SX2+. Controller is the DDCSC3.1 running the latest software 2019-10-10-112.

I intend to use the Tormach TTS system (or a copy!), and No I will not be buying a Tormach!
This should allow me to accurately remount tools into the spindle

I am finding things VERY confusing. I am running this code:

T2 is 21.32 mm shorter than T1 but I have to set T2 to -41.32 in order to come down to workpiece Z0

N010 G17 G21 G49 G54 G90

(Set #267 = 0)
(Set #268 = 40 T1)
(Set #269 = -41.32 T2)
(Set #270 = 25 T3)
(Set #271 = 30 T4)

(Establish X,Y,Z with tool 1)
(Top of workpiece is Z0)

N020 G00 X0.0 Y0.0 Z0.0

    F 250
    M03
    S 1000


N030 G00 Z20

N050 T2 (is shorter than T1)

N060 M06 G43 Z0.0 H2 (4mm short end mill)
    (Tool lowers by 41.32mm to workpiece Z0)

N080 G01 X10.0
N090 G01 X0.0

    M00 (Pause b4 G49)

N100 G49

N110 M00 (Pause T2)

N120 G00 X0 Y0 Z0

M30
%

That works but if I change N030 to Z30 the mill would drive 10 mm into the workpiece.
Luckily just cutting air at the moment.

Any thoughts guys?

Cheers

Will
