Hi All,
I am in the process of quoting a job and I am having difficulty in working out how I am going to measure a feature.
I personally haven't come across anything in over 20 years of machining that will allow me to measure an internal groove diameter to the accuracy that I need. However, I am a long way from knowing every piece of equipment out there and so was hoping someone might be able to suggest something I haven't thought of.
I have sketched up the part we are looking at with the relevant features. I am looking for something that will measure the 18.5mm dia internal groove to an accuracy of 0.013mm
I should say, this will be for a quantity of parts, so I am not looking for a quick fix as I know I could have used something like ball bearings and a home made plug gauge for a 1off. I need a proper solution, something like a 3 point bore mic but for grooves.
Any help will be greatly appreciated.View attachment Sketch.pdf
