I agree with Gcode above, using ID jaws clamping in the big bore.

I could not find a way to do such wizardry. There only seems to be options to rotate and drag. If it was mirrored would that not be breaking the left hand rule (sic) for cnc? ... or right hand rule for those that will google it.

Shameless plugging on a 4 year old thread...tsk,tsk, tsk

My guess would then be that you do not have a 4th axis defined in your machine definition manager.

Check Axis Control page

I have found that if it does not hit the ledge then it is a culmination of stock to leave and Minimum toolpath radius on the cut parameter page. I do find myself adjusting the radius to get the tool to fit. With the stepup and stepdown, it took me a while to grasp what was going on. Initially what I was doing was taking total stepdown minus floor stock and then dividing the result into equal steps in order to reach the bottom. Once I started playing with the stepup option all my extra math stuff went away...twas a revelation I tell you.

I suggest leaving a little more than usual for your finishing pass and, if you can, use through tool coolant for the drill and drill with no pecks. If no through tool for the drill then peck at least 1.5 x D.

I almost always do this type of thing once the code is posted through CIMCO edit or any other application (word, notepad, etc) To me it makes no difference whether i am typing it out in Mastercam or the editor.

No problem.

Go into machine definition manager(1) - expand Mill Spindle Group(2) - Right click VMC Tool Spindle(3) - click on properties then change(4) 1 2 3 4

I find that putting a value into 'Stepup" nets the desired results. If I have no features that need ruffing above my Stepdown value then my Stepup=Stepdown. If there are things like bosses or rads/chamfers then Stepup is about 10% - 20% of cutter dia

...hmmm... in that case draw a silhouette boundary of the part then try measure that way

in 3-d mode - analyze - distance - hit I (intersection) top and right edge curve for 1st point - hit I (intersection) bottom and right edge curve for 2nd point

This is applicable to most, if not all, windows based software.

I am not having issues with this. One thing to note is that I can only change values in the yellow boxes not the blue

...uhm...

I would start by checking the your CAD to make sure dimensions are correct, start there because it's a quick check. Next; check to see if tool centre is in line with chuck and there are no offsets effecting the tool - x wear offset - tool radius offset. Below is from Google Translate so if it does not make sense...meh.. Je commencerais par vérifier votre CAO pour m'assurer que les dimensions sont correctes, commencez par là car c'est une vérification rapide. Prochain; vérifiez si le centre de l'outil est aligné avec le mandrin et qu'il n'y a pas de décalage affectant l'outil - décalage d'usure x - décalage du rayon de l'outil.

The wear comp goes the same direction as your travel, so with ID start at negative wear and move up. For OD the opposite, start at positive wear and move down.

Well it would be if his question was CAM related...

I have mine set as follows, apologies for the sh!tty screen grab

This is what we use Insert https://www.iscar.com/eCatalog/item.aspx?cat=6003105&fnum=1431&mapp=TG&app=51&GFSTYP=I&isoD=1 Holder https://www.iscar.com/eCatalog/Family.aspx?cat=6003105&fnum=1431&mapp=TG&app=51&pageType=4&rel=T

You could substitute the G0 sub side to G1 with a high feed rate.

Pick +D +Z in your planes manager

In previous versions yes, but not in 2022.
