New to the O-Inspect

[[Ra...]]

I'm new to programming the O-Inspect and I forgot how to setup the CAD model so that I can write a program using the camera. How do I line up the camera with the CAD model if I don't have the block yet?
I have the CAD model loaded, but I want to write a program ahead of time on the block and I'm not sure how to pick up my alignment features with the camera. I have written programs for the Contura, but the camera is a new thing to me.
Can I get some insight into how to program this block using the CAD model and the camera feature?
Thanks,
Rachel

Unfortunately a lot of the camera programming has to be done at the machine. You can select features and create your base alignment. You can do all the tolerancing too. But the strategies are going to have to be done at the machine to get the light settings and threshold settings right. After you do it a while, you might be able to save a few light settings that you know work for certain cases and can add them in before you run it.

Just program it like you would the Contura, only you will have to limit yourself to 2D features (Besides planes that are normal to the camera view.) when you are using the camera.

I never program the O-Inspect by CAD model, except maybe when there are more tactile than optical measurements.

Calypso features a lot of quirks when programming optical features on the CAD. To name just one: you can't program circles etc. exactly on an edge, simply because you can't select it. So you have to put it a bit below and then adjust the Z nominal. When I was still new to the O-Inspect I did that for a program whose optical points had to be exported as files. I then discovered that the Z coordinates in the point files were all offset by exactly the difference between the edge and the point where I had clicked in the CAD model. This offset is stored somewhere in the inspection file and can't be edited by the user. So once it's there it stays and can cause a number of problems like the one above.

We have a 2 vision systems, unfortunately neither are Zeiss, but similar to what Bret & Norbert said we only program with actual finished parts.
Even 3D printed parts dont work for us.
Additionally since we machine plastic, different colors provide their own set of issues where programs usually cant be copied & pasted for similar part sizes because lighting on a yellow part and lighting on a blue or brown part aren't the same.

Actually, if you go to CAD - Creating Features, and turn your model to wireframe, you can select the spline at the top or bottom of the cylinder/cone. In addition, what a lot of people do, especially if you are using back light, is use a auto-focus point on the edge and measure the circle at that location. The Z nominal doesn't mean anything at that point.
