Looks good to me! Sometimes the backplot in NC Editor is all the verification you need.

Well, that didn’t go quite as planned! 😂

Originally, I was trying to avoid tearing down my riser and baseplate, so I made a zero-point plate for my 3-jaw chuck.

Got everything mounted, dropped the part in, and realized two things. The setup was too tall, and the through-bore in the 3-jaw wasn’t nearly as big as I thought it was. 🤦‍♂️

Sometimes the plan doesn’t work out, but at the end of the day, all that matters is we got it done! 🤷‍♂️

Porting made easy!

Scientific Cutting Tools, Inc porting tool getting it done in one shot. Form tools like this are a great way to condense multiple toolpaths down to one! 👌

Plenty of clearance! Verified it in sim and sent it. 😂

This 25” diameter table is just too damn big. I’ve had to get real close one too many times and have had to extend tools farther than I’d like just to get enough clearance.

Looking to replace it with something smaller.

Repeat job that I’ve been buying full length bar stock for and cutting to size myself.

I try to avoid using the saw as much as possible, and after cutting up 5 or 6 bars over the last year, I decided I was done with that. 😂

Started playing around with quantity price breaks and found the sweet spot where having the supplier cut all my blanks to length was actually $20 cheaper than buying full length bars and cutting them myself.

These parts still require a stock prep operation before machining. The next goal is to eliminate that operation entirely so the blanks can go straight into the UMC.

My favorite type of machining and my favorite material, all wrapped into one! 😂

Fit and function were the only things that mattered on these rings.

I almost ran these in the mill just to bother some of you lathe dorks 😂

MRZP Calibration

Once a month, I run this test cut and probing routine to verify and update my MRZP values. The entire process takes about 20 minutes.

The routine machines features at B0° and B90°, with C-axis positions at 0°, 90°, 180°, and 270°. It then probes the machined surfaces and automatically updates the MRZP values based on the results.

Before adding this routine to my UMC, I used the factory MRZP calibration. The results were never great. The blends and location between different orientations weren’t terrible, but they were noticeable.

Since switching to this method, the difference has been night and day.

Full tilt!

Didn’t originally plan on machining this much in the first OP, but every time I take another look, I find myself adding another “might as well hit that feature while I’m here” toolpath. 😂

At this rate, there won’t be much left for OP2!

Programmed and ready to start running tomorrow.

We’ll see how this goes, no matter what order of operations I go with, it seems like it’s going to get questionable.

At what point do you buy extra stock?

Every order? Only on certain jobs? Do you factor the cost of that extra material into your quote?

The majority of my work is low quantity—usually less than 3 pieces, so I rarely buy extra stock just in case.

I also have the advantage of being able to get replacement material in 1–2 days if something goes wrong, so that definitely plays into my decision.

For me, tying up money in extra material that will probably end up sitting on the rack doesn’t always make sense.

What’s your approach? Buy extra for insurance, or order only what the job requires?
