Hey everyone,
So glad I came across this forum. I hope that you can help me with this project and I can get it built. I'm working on a tool to help me at work be more accurate and more efficient as I do my quality inspections.
Essentially what I need to do is design a tool which will help me to accurately and quickly determine two measurements: dip and warp. In order to do this I intend to build a frame which I can put the varying products in, and have a vertical row of measuring sensors (still need some advice on what the best sensors to use might be... the surfaces will not be reflective). I figure with 10-20 data points (adjustable based upon the height of the product) I can plot a curve and determine the depth of the concave surface. I need the resolution to be accurate within .001inches. What will make this difficult on the math end of things is that the surface being measured will not always be true to the y-axis, and so the top and bottom points will need to serve as the reference against which all the calculations are done. Here's a rough sketch...View attachment 60719
Thoughts on type of sensors necessary, price point of those sensors? What type of "brain" I will need so that it can record and process these measurements 100x/second as I rotate the item, store the greatest depth in the surface, and display the max on a small digital screen?
I'm sure I've left a lot out, and I know I've been slightly ambiguous, but ask away, or direct message me and I can try to give more detail.
