The end result of all this is that you'll be able to drill/bore/face DEAD square to the table at least for an inch or two. You can NOT achieve the same PERFECT result with a cylindrical or 90 degs square short of some very serious irritation and even then, IF SO. The ring method, if intelligently used keeps the machine VERY close to working position. The others keep it FAR from that.
An even BETTER post, thanks!
But right HERE is where "compensation" already enters!
You niggle, nudge and dead-blow-tap to line the DI on the God of the spindle up to near-zero deviation.
And then? AS you start to tighten the clamping fasteners?
EVERY machine
moves, and moves a tad DIFFERENTLY than the one off the line, adjacent serial number, even if BOTH of the f*****s are BRAND NEW and still "Virgin", never yet made first-chip!
Which they are basically "never" in real-life.
Quite the reverse. Worn out hoors!
NOW you learn to "compensate" so the DI will be dead-nuts AFTER the clamping is completed.
In the fullness of time, you will come to "marry" that machine-tool, and hold it's personality and quirks in YOUR memory so it becomes second-nature. Different machine or new job? Introduce yourself to the ways of a new partner.
"First comes good."
"THEN comes
fast"
Now you are EARNING your pay, no longer just a break-even student.
You KNOW you have crested the hill when a Foreman who came up through the ranks off the shop floor himself, now twice your age - or a LOT more, yet - ASKS you instead of TELLING you, and then discusses and agrees a reasonable way to tackle a challenging tasking.
You have
demonstrated that you UNDERSTAND, and have the knowledge and judgement worthy of his TRUST.
Between your ears. Skill between your HANDS
follows, it does not lead.
No time to get cocky.
You still have MORE to dig out of his brain and transfer to your own one! And he had best not be your ONLY source, either! Some crotchety Old Fart is the shop's most notorious ASSHOLE? Yah, well.. he knows SOMETHING you do not YET know!
How can you "xerox a copy" and make
use of it? And does he know MORE than "just the one new thing?"
Useful skill you wouldn't want to have to put into a book? I learnt to IGNORE the NASTIEST of "denture breath" and even flying spittle!
Got me fast-tracked tool & die training from a Master's, Master's, Master in his mid and late 70's. Then another in his 80's, and then .. the only "A" on the final and one of two for the course, one of the finest, most expert, and decades-long experienced minds in Money and Banking of the age. Brilliant guidance. If one could but STAND the SOB!
Well. It wasn't as if I had to have SEX with any of that lot, was it? It was America and ancient grease. Not ancient Greek in Greece!
What a(ny) human can "do" is largely a product of what that human "has come to KNOW". or is willing to learn NOW. Because he knows he will be better-off.
"Learn" by whatever means, and from any and EVERY source within reach of his ever-acquisitive mind.
So long as it is FASTER than the OTHER guy who wants access to the nicest looking food and the tastiest wimmin.
Or is it the reverse? Can't remember EVERYTHING, can one? Keep it simple.
BOTH will do just fine!
Anything LESS important.. money and similar s**t... will just happen to fall in line with minimal fuss.
Really. It just
does when you are too busy staying happy-healthy learning and growing to stop to whine ... and blame some other guy.. if not "management".. if not the whole dam' universe.
And just which one of those three actually gives a measureable shit about YOU?
Would you believe the SAFEST odds ..... are with "the universe"?
If only because it is less resistant to change.
