Crosshairs

[J Temmen]

I am measureing a lot of manual points due to the type and repeatabilty of my part, when I am programing these points the crosshair is nice and big, however, when I execute the program the crosshair reverts back to the very small one. Is there a way to get the large one back during program execution?

Hi James, I'm not seeing this (in V4.1 at least).

Can you clarify - are these Edge Point features measured as "Manual Targets"?

At execution time, you should see two round handles on the cross hair target. The green one is the handle to rotate the cross hair. The other handle (in the colour of your cross hair) allows the cross hair to be made bigger.

Another thing that might help - you can also change the colour of the cross hair (in the probe toolbox - Define Targets page) to make it stand out better on the surface.

I'm using v4.0.

What I am tring to do is position the probe to measure a read point at the cursor position, but during execution the crosshair is small and hard to locate, when I am programing initially the crosshair is adjustable and thats how I want it when I run the parts. Is that possible. Also, is it possible to input into the program the use of the protractor gage or any of the other gages?

Hmmmm...you've confused me. Which feature types are you using then?

When you program the features (e.g. Edge Point, Circle), the cross hair you see is the same that is used at execution time. It is these crosshairs you need to be aligning to the edge.

Vision features can operate in three "modes" of acquiring data. The first, and default, is Automatic Target. This uses image processing to find the points. If the edges are so bad you can only reliably find the edge manually, then you can swap to Manual Target mode (cross hair). In command mode, toggle the AUTOMATIC TARGET parameter until it says MANUAL TARGET. This sounds like what you need, as this will have the adjustable big cross hair.

I think the cross hair you're using/referring to is the small center of Field Of View indicator (which is not resizable at present - I will log it as an enhancement).

Lets say I have a corner that I want to find in X and Z. I can position the large adjustable crosshair on both edges and create a readpoint that gives me their intersection. The only problem is, is that when I run the program I get the small center locator as my crosshair and my readpoint becomes a best guess point.

Can't you just program two vision Auto Line features (Automatic Target if the edge is clear enough, Manual Target if you're struggling to see it), one on each of the edges, and then construct the intersection point?

This way, you don't need that center cross hair or read point.

Re your earlier comment about the Gages in the program, you can currently use the Circle Gage and Line Gage. If you program an Auto Line or Auto Circle vision feature, and select "Manual Gage" (I think it might be called "Manual Adjust" on V4.0) from the "Automatic Target/Manual Target/Manual Gage" pulldown list on the Probe Toolbox "Define hit Targets page".
