Who has layout inspection experience?

[Schrocknroll]

Have you used pi tapes, cadillacs, sine plates, scribed layout lines, etc.

Started out on the table.. No pi tape tho.

Layin' Out

Yes I are
am
do layouts every day
+ cmm, too

[Mark Farren]

IMO

In my opinion , everyone should have a lot of layout experience long before you ever sit down in front of a CMM!

As a tool maker, I did surface plate layouts, before taking my first off to the cmm. We all knew that the cmm was inaccurate..lol. how could we be wrong??????? However the cmm reports were very close to my measurments. Sine plates, indicators and height gages work, if you know how to use them.

Never even heard of pi tapes. But I started on a plate. I had venier everything. learned trig to use sine plates. had to level a part to so true positions on bolt hole circles. Bore runout. Loved optical comparaters. Hated and hate even more today. Blue & Scribe. Though they ask for less and less each time. Check gears using pins. I can still double check almost all the diminsion from a CMM with a plate layout. I don't tell someone its wrong until I prove to myself that its wrong. I have the respect of all my men, always have always will. It takes alittle extra time but its worth it. Thank god for old timers who are willing to share knowledge. Kinda what we are doing here today.

I agree , really helps on basic BP reading ,setup and understanding.

old school

When I first started in the biz, nearly 20 years ago(ouch! ), the old timer that was training me had a scope that mounted on a height stand, like an indicator does, and you could locate sharp edges and so forth with it. It had an adapter that mounted on the cadillac that had cross hairs on it so you get transfer your measurements. It was pretty cool and pretty da*n accurate. Sure wish I had that now, just to prove a point once in a while!

[Paul Sarrach]

how about a hole center finder?

[ag162]

I could not imagine doing this job without having the knowledge the old timers shared during my apprenticeship. If you can't do a plate layout, how can you support an out of tol part? DUH,,,,the computer said it was out. lmao! then, if you are doing a layout with a print and no cad,,,,you still need to have the background to pull some of the dimensions. I even did some reverse engineering with a WEDM. That can be a little time consuming and tricky. XY, UV adjustments.

Yes. All of the above.

[Paul Sarrach]

How about the benix cordex machine. the first CMM? It scared the real old timers, saying it and the CMM will never catch on.

OH man. I forgot about that. Started out on a Boyce Mdl. 501. Cordax Machine

Used the OFI language, function numbers! Oh what fun that was. We've still got one here!

[hoist bouncer]

20 years ago vernier height gage, sine plate, dial height gage, digital height gage with hole gage and indicator, dial indicator- made extension for height gage for the indicator to stick wayyyy out there in order to get some boss depths. trig book and calculator
