A little validation checking

Validating the accuracy of the Pocket NC

This is a positional check for X and Y. Are they centered about A and B Centerline? There are 2 checks that can be made. 

1) Rotating B constantly does the center hole run TRUE as it is spun? It's really about how concentric is the platter backside bearing to the front side locator hole?

2) Once that is true rotate the indicator in the spindle 360

This is a positional check for X and Y. Are they centered about A and B Centerline?

My ol' pappy use to say...

A story about my Dad and the guy that went on to invent LASIK Eye Surgery
If you google KOPF VITROPHAGE PEYMAN  you are going to see an early patent that was made with my fathers business www.kopfinstruments.com and http://www.drgholampeyman.com/

Now this was the first patent developed by Dr Gholam A. Peyman in conjunction with my father David Kopf. It was for an instrument called a Vitrophage. Who's purpose was to remove cataracts from the eye. This was an advanced piece of equipment for it's time.  It mechanically was feed in to the side of the eye. it was the size of a horse injection. It was controlled by the doctors hand and chopped up the cataract into small pieces, vacuumed them out and replaced the particle with an equal amount of fluid. Sounds scary right? Like Doctor McCoy on Star Trek said of primitive medical equipment. Dr Gholam A Peyman went on to develop over 145 patents. He was recipient of National Medal of Technology and Innovation, the nation’s highest honor for technological achievement, bestowed by the President of the United States, President Obama in 2013.

Bob Dylan - I shall be free #10

What song would you pick: "A day in the life" Or "I shall be free #10"?
I'm old, hopefully not as old as you haha! So mom took me to see the Beatles at their debut LA show Hollywood Bowl in '64. The same place dad showed off his Ferarri at the concurs car show. Well I've been a beetles fan since I was a kid. But Bob Dylan obviously was on the airwaves but not as profoundly as John Lennon boasted himself to be. Yet now he won a Nobel Prize in literature! So listen to this song "I shall be free #10" by Bob Dylan  https://www.youtube.com/watch?v=dW3qgP19OBE

5 Axis Artifact

This is a 5 Axis Test Artifact Concept

The arrows on the sketch show the direction a tool will point while cutting this part. In some cases the part is cut with the side of the tool. Other areas are with the tip. And these cuts are then measurable. Typically the cuts with the side are more predictable with tool length setting not critical.

Here is a word document conveying the scope of this 5 Axis Artifact
