KERN IT UP.
Grimsmo machines his own ER 16 collet for the KERN! Wait until you hear about how he made this monolithic-integral ER. All this talk about holding parts on center brings back a good ol' Memory with Marv. Saunders recounts an accuracy test for cylindricity on the KERN--Swarf VS. Polar Interpolation in Garmisch- Partenkirchen.
Threadmilling. Single Point or Proper Threadmills? Tool Standardization?
The guys dive into threadmilling and tooling up machines; including single point versus proper threadmills, tool deflection, and whether or not to buy or DIY Collets. Regardless, the process needs to be reliable AND no matter how magical the brand of machine, it's still subject to the laws of physics.

HEAR ME OUT: The Synergistic Effect of CNC Theory.
Saunders asks an interesting question, "Could the collets be made on the Nak?" At first it seems like an impossibility but with an open mind, new ways of thinking can lead to solutions you never could have imagined.
Cogsdill Diamond Burnishing Tool on the Tornos: YAY or NAY?
Grimsmo shares an update on the SAGA pen clips.
Saunders teases Grimsmo with the mind blowing video that's in the works. This Covid-friendly collaborative video about MetalQuest's INDEX MS40-8 will be about the harmony between machine capabilities and maximizing workflows. It's hard to imagine the back-work, which is all the more reason it MUST BE SHOWN! Get ready to reduce cycle time, increase output, balance cycle time between spindles, and more!
Covid and Manufacturing: BIG GIANTS FALL HARDER.
No one wants to speak too soon but there's been a sigh of relief that smaller manufacturing businesses haven't felt the same pain as the larger, often over-leveraged, companies. Seeing a "company consolidation" flyer in the mail for an aerospace company feels....weird.
Does Grimsmo regret the large financial risk he took with the KERN given how 2020 has panned out thus far?
TOTALLY REDEEMED AFTER BEING REAMED.
A few episodes ago, Saunders called Grimsmo out for committing two cardinal sins of grinding. In order to make progress on the Rask, he decided to forego dressing and balancing the wheel before grinding the knife blade.
Maybe Grimsmo's method of madness was intentional all along or maybe it was pure luck that resulted in the perfect recipe. EITHER WAY, IT'S FANTASTIC!
Surface Finish Factors
You hear about tool deflection, speeds & feeds, material type, and machine kinematics but what about presenting an even chipload/tool pressure to the cutting tool? Devon Dupuis from Autodesk and Saunders are collaborating on an OUT OF THIS WORLD part that relies on getting that chef's kiss finish.

ERP: Permanent Product and Material Location
A big part of implementing ERP is deciding where things will be stored. It might sound easy to have a permanent location for parts and material but Amazon outright rejects that logic. The key is to make sure the item can be located anywhere at anytime.
The Johns wrap up this 190th episode with probing, tool break detection, and what's on tap for the day!
