Sup CNC ZONE!

[TheMachinizt]

Hey sup guys. I was just online looking for CNC stuff and came across this website. I didnt know there were websites like this out there. Amazing! And HELPFUL.

I have a quick question. I havnt touch a CNC machine in about a year and kinda forgot my way around the G codes. Ive read "G Codes" list and recognize some of the G codes but forgot what most do. Anyways please bare with me.


Lets say im using FANUC controls.. I found x0 y0 z0 at so and so point. Im using G54.


Whats the code to tel the machine to goto x0 y0 z0 so i can double check my start off point?



If i can remember.. it would be something like this..

G54 G00 G90 G43 X0 Y0 Z0 H1 can someone verify this for me if im correct or wrong.

and what does the codes in this line mean exactly. PLEASE tell me in a way that doesnt sound so complicated. break it down for me please. Ill really appreciate it.


I already know G54 means use G54 work coordinates. G00 means Go.
I dunno what g90 or g43 or H1 is... i THINK h1 is Tool 1, Please HELP AN OLD TIMER OUT... Appreciate guys!

Just googled RS274. This will refresh your memory.

More detailed stuff, particularly the NIST stuff which is easy to navigate.

G54 is use work coordinate system 1, which should have previously been set to your part 0 location.
G00 is rapid move, remember it is non-interpolated.
G90 is move to absolute position.
G43 is Tool len. comp. in the + dir
H1 is the stored value of the comp.
If you want to return to machine reference zero point, use G28.
If you want to check that the G54 zero point is OK using that code, it is handy to have feed rate overide or rapid overide, many MTB's do not install a R.O. , when G0 is used it is handy to be able to crank rapid or feed down to 0 to stop the feed in motion and check the distance-to-go value if displayed.

ok im confused. When i have the machine at its zero reference point and i use the handle to move it out of 0 x y and z then i use G28 Code to get the machine to its zero reference point it works. But if i use G54 to XYZ 0 first then try to use G28 to goto machine zero refrence point. Nothing happens. What am i doing wrong?

Can you explain to me more about g43? and H1 im a little lost there. Appreciate it.

So ... G43 is telling the computer to read the tool lengths in the offset for whatever H is

for example.

G43 H1 = Read tool 1 lenghts. and G43 H2 read tool 2 lengths. Correct?
