I'm currently working with an Absolute Arm 85 equipped with the RS6 scanner. I was wondering if it is possible to create a program that calls for the part to be scanned, then flipped mid execution in order to account for tolerances of the entire part. Basically I am trying to scan and check an entire part in one chunk of code rather than having to perform two separate scans.
Matthew D. Hoedeman is there any way you could give me a little more insight into leapfrog? I am trying to use it for a different part now, and the f1 help page for it on PC Dmis is not really helping me.
Essentially, I am trying to perform a bunch of surface profiles on points I have picked. I am able to do this on one side of the part, however when I go to do the other side it runs but it lists every point on that side and says it needs more scan data. So, for some reason I'm not collecting data when I scan for a second time. I feel like this may be a good situation to use a leapfrog, however I frankly haven't been able to figure it out. If you have any advice for me that would be appreciated.
Obviously I encourage anyone to jump in on this discussion I only tagged Matt because he originally brought the idea of leapfrog to my attention.
I've used leapfrog, but not in a long time, but.... I made up some 'pucks' and epoxied them to EDM magnets (very VERY strong for their size)
The pucks have a cone WEDM'd into them, that is a 3-lobed shape (think more of a triangle). This shape makes it to that a hard probe can only make a 3-point contact, and makes it so that it doesn't matter at what angle the probe is at to get the same data, and yes, it does locate the probe 100% in 3D space since it is being put into a 'cone' shape. This is supposed to be the most accurate, but the next 'down' is 3 sphere.
INSERT ~ ALIGNMENT ~ LEAPFROG
Brings up a menu where you choose what kind of features you are going to use. I've only ever used the 3 point method, so I mark that box, then click the MEASURE ALL button. NOW is when you measure the 3 points (or spheres). Once you measure the 3, it tells you to "move". So you move (either the part in your case, or the entire arm if for a really big part) and measure the same points (spheres) in the SAME ORDER. Once done, DO NOT CLICK OK on that pop-up!!!!!!!!
There is an area that tells you how wells the 2 sets of measurements merge (how close "before" matches "after"). IF you are happy with the values, click ACCEPT, then it will ask you if you want to add the leapfrog to the program, tell it yes, and you should be ready to go.
