Most CNCs have fixture offsets and default to G54. They then provide G55 - G59 typically. In MDI call G54. Jog to where you want X Y Z zero and set all axis to zero. Call g55, move to home position and again zero the axis. You can also specify those locations numerically.

I am casting an aluminum housing for a lathe spindle and bearings from LittleMAchineShop.com to use as lathe and 4th axis.

Lots of activity here. Everyone staying home and working with CamBam?  I am still going to work but if we shut down that will happen for me too as I can work on my CNC in my garage.

I changed jobs and have no sick time or vacation time accumulated yet and I haven't passed 90 days trial yet so I don't have much choice.  However they are very happy with my work.  Working on Chinese built production machines.  They are so badly built in every way that it is hard to imagine!  Nothing I touch is has been right and needs to be redone.  Broke a linear bearing shaft in a punch press die set yesterday and after less than a year of intermittent operation all the bearings and shafts are completely shot.

I think you need to change your work plane in your CNC from the XY to XZ or YZ. G17,18,19 if I recall correctly.

Gonna have to try the AlumaCut as aluminum is about all I do.

You don’t say what kind of cut a pocket is very different than a profile. CamBams stepover is % of tool diameter and that stepover in inches would need to converted to %.  The problem in pockets is when the tool goes in a corner at that stepover and contacts the material for 90 degrees or more. The troichoid MOP plug which I tried for the first time recently allowed a much higher feed rate and no sudden load increase in corners. My wimpy machine sounds a lot better too.

Same for me when I drill. Drilling is all about chip control. At my new job I am setting up 2 axis drilling machine that drills 102 holes in a polypropylene pipe using three spindles and a peck cycle.

So today I am using a Trochoid pocket for the first time because I have to remove a fairly large deep pocket.  Just wanted to report how great it works! Nice and gentle on my machine and very fast.

Thanks for this MOP

Yep rotating the nut instead the screw eliminates screw whip on very long screws. Only downside is that motor weight is moving and more moving cables.

Use a drill MOP with spiral milling.

How high did it go?

I use the Cermet carbide blades on my table saw and as you found they do an amazing job on steel up to a 1/4” or so. Solid materials not so much.

Teak is loaded with silica so carbide is really the way to go.

This forum is so relatively free of spam and arguing that it is hard for me to be upset about it.

Thanks David!

Frank,
Every CNC machine I have run does it the way you describe. During that move to the Safe Z is when tool length compensation gets applied so if you accidently put in a long tool or forget to set tool length you'll have no chance to catch it before you damage your part. In many instances like if you paused a program, rewind and restart the Save Z move is upwards as expected.  I think you are trying to use the tool change Z position to get around clamps and such and that really not what is intended so you should proceed with caution.
