hello
yesterday, i was a bit in a rush, but i liked the photo shared by kenny
pls, what means : tts ( post #2), ets ( #4 ), pdb ( #9 ) , tlo uccnc ( #11 )
ok, back to tool ( offset ) and part zeroing ( program zero ) :
1) shifting axis origins ( kind of grid shift )
1.1) z offsets on mills = distance ( tool nose , spindle face )
1.2) z offsets on lathe = distance ( tool nose , turret face )
1.3) program z0 on mills = distance ( part face , table )
1.4) program z0 on lathe = distance ( part face , spindle face )
* all this allows to :
... declare offsets and programZ0 only with a (depth) caliber ( which comes in handy, for example, if you can not use the tool setter in the middle of a job )
... syncronize machining cabinet with tool presseting equipment, and/or virtual cabinets inside simulation software ( like someone said, i like to declare Z0 when sitting comfortable at my desk, and not being near the machine ... i can do it remote )
... build confidence, since program zeros and tool offsets, no longer represent a random number, but an absolute distance, that can be checked inside the machine
like this, one should be able to estimate absolute distances inside the machine ( between tool edge, part, fixture, walls, and working area limits, etc ), only by looking at the coordinates displayed, and without looking inside the cabinet; obviously, is not a must to work like this ... for example, i can draw machine position with 0.1 accuracy, only by looking at the coordinates displayed on screen ... and viceversa ( pre-simulation; so far only for machining planes, likes xy xz zc, etc, not fancy random 3d perspectives )
2) pls check attached image, i hope it makes sense
<0.01 accuracy
3) a while ago, i read a post from someone that used paralel glass lens on the part face ( or whatever reference surface ), a source of a light, and was able to detect contact between tool nose and lens, only by watching how fringes were changing
kindly
ps : i saw later that this is a tormach thread, i don't know, maybe is ok ... why is this forum called " personal ... tormach personal" ? is like the machine is your friend, or something ...
