This is how I looked during a 12+ minute cycle on the mill:
So, what better way to entertain myself than to guess the spindle speed based on the MERRRRRP pitch??
You can play along too!
Here’s what I had to work with:
Mary Jane is working on the mill in a factory. She hears an E pitch three octaves below concert pitch A. Knowing that the pitch is created by a tool spinning at a certain speed, and knowing that concert pitch A is 440Hz, how fast is the tool spinning in rpm (rotations per minute)?
Easy peasy! But I have not taken a math class since senior year of high school, over 10 years ago. Granted, the last math class I took was multivariable calculus… so I have a decently developed conceptual grasp of math, but I’m very horribly out of practice. When you’re done solving the problem, scroll down to see how my poor brain stumbled through.
Only 9 rpm off! Enough to break a tap, sure, but still! That might have been the most gratifying use of absolute pitch in the history of MJ.
Goodbye, factory! I’ll miss everyone there very much.
I’m shifting my evening focus to violin making (and hopefully not failing to meet my posting schedule here any more).
Now let’s revisit the very beginning of my little CNC adventure.
Check out my awesome view!!!!
And let’s wrap up with some excessively smiley factory selfies! 😀 😀 😀 😀
I had a good time.
CNC is a delicate subject in the violin making world. I work in a factory operating CNC machinery, but please, chill out! This is all I do there:
See? That is not a violin.
In fact, I don’t even really know what it is….
Note: I may or may not have drawn this at work while waiting for a long cycle to finish. 😛
Yeah, that’s right, Frank Gehry. I found your Pritzker Pavilion in the dumpster.
Let’s play a little game.
Got it?? #6 might have required a little reverse engineering, but that wasn’t so hard, was it? Where will MJ’s nonsensical train of thought take you next?
