Metrology equipment for lab
(OP)
Hi there,
We are setting up a small workshop with a drillpress, tools, benches, cutting machines... in order to be able to do small tasks. For more professional parts we have a mechanical workshop with experienced people working there (with lathes, milling machines...).
I've been thinking about getting measuring machines to check machined parts (or even some composite components we make).
What would you recommend to set up a small metrology lab?
- CMM machine
- Roughness surface tester
- Dial indicators/supports..
thank yo
regards,

Does the CMM need a lot of training?
With the Optical comparator it seems one can not measure perpendicularity, parallelism... it seems a bit limited.
My point is we paid 700 euros per part to a company for precisely measure two parts. With 80 of these measurements (ok, a lot, but in a long ternm) we can already pay the CMM

The CMM will also need a conditioned room and a service contract.

Since the original spec didn't include photos of example parts or drawings of same, it is hard to know what may be valuable to inspect them. That's why the optical comparator was mentioned. It can be used to verify items that a CMM cannot do, but if you don't have parts that need it, there's no reason to have one.

Provide more details and better/relevant suggestions can be made

Also, CMMs are alright but unless you know what you're doing with one and the limitations of only measuring points, you can make a right mess of measurements.
A pair of go not-go pins or a bore gauge is going to do a far better job of measuring a hole than someone who thinks they only need two points on a CMM to measure a hole diameter.

Here a picture of one part we produce, carbon fiber coming out of a mould:
We have moulds with very high accuracy and we want to measure the result (this part was sent to a company to be measured and the measurement cost around 1000 euros)
Here half of the mould (when full it has a square shape). We need to measure it when mounted to see if the mechanical workshop did well their milling work
If we want to see how flat are the faces, also how much perpendicular; I understand we need CMM

Seems to me there are several ways besides a CMM for measuring flatness:
> laser or mechanical profilometer
> dial indicator
> optical flat

Generally, measuring flatness with a granite plate, a height gage / indicator stand and a dial indicator would be easy. Perpendicularity can be verified using a machinist's square and a feeler gauge.
However, since you haven't specified the precision you want, there's no way to know if a cheap setup can attain that goal.
