Calibration of the 1mm tip on my WIPS probe kept failing. Renishaw support gave me instructions on how to fix this over the phone and now I'm up and runing!
Thanks for the video, I'm looking into getting a probe and I would need the 1mm tip to probe certain features. Glad to avoid a few phone calls whenever I can.
I'm a CAD/CAM SME but huuuuge fan of Peter Norton and the work of his generation. Imagine my surprise when I learned that a guy that talks about CNC probing wrote Norton Commander. Shocked 😲
there's also a mechanical tension adjustment inside the OMP but it's a pain to control. I use a longer 150mm ruby stylus with a particular workpiece and they realllllllly recommend loosening the internal tension for that, since it can cause premature wear on the ball. I went ahead and did it, but then reverted back and instead just used different trigger feedrates exactly like you described. It's theoretically the opposite with a stubby stylus (wants a stiffer tension) but it probably doesn't matter since the materials are different for that stylus anyway. I have a 1.5mm stylus myself but never used it, just bought it for fun 😆
That's interesting. I certainly wouldn't want increase the tension for this stubby probe because the shaft is even smaller in diameter (I'd have to look it up), which means it could flex more easily.
With the variety of work I do, I change probe tips and sizes regularly to reach the features I need to probe. This is great advise if your planning to change probe tip style permanently.But if your like me and changing to different sizes and lengths regularly, it's more efficient to just slow down the feed rate overide while probing with the extra small or extra long tips.
Nice. Changing the feed override would have been a quick way to test this. Since I want to do in process inspection with the 1mm stylus, I'll need to keep the lower feed rate in the macro. But it's nice to know about that trick. Thanks.
Another interesting question is how to reduce the speed at which the tool drops on the tool length sensor. It goes so fast that for 1mm end mill it can break it.
It might be the same. The fist touch speed applies to X, Y and Z. I haven't tested that. But you can call Renishaw and ask. If you do, please reply with at you learn. Another viewer mentioned you can use the feedrate override to slow down all probe movements. I have used the toolsetter with a 0.02 inch diameter end mill.
Hey, love you videos on the injection molding. Would the process be food safe? would it just come down to what plastic resin pellets are being used? Thank you
Thank you! Yes injection molding is used all the time to make food-safe products, such as plastic spoons, knifes, etc. And yes, it's bout using food safe plastics.
I'm not sure _why_ 1mm _vs._ 6mm tip should require a different approach speed for the second contact. It seems like both contacts should be the same, and still doesn't explain why the difference is diameter-dependent.
It's because of the short length. So the same speed of travel causes the angle to change a lot faster. The trigger is based on angle change. Hence, with the angle changing faster, it can't keep up. I didn't think this through until you asked that question, as it would have been good to cover this in the video.
