I spend most of my time looking after guys running the machines, trying to keep a handle on things, and fixing the machines when they break down....which lately has been quite frequently I only really get into it anymore if its something tricky, or if I'm training one of the newer guys on something, or if its got to be done YESTERDAY LOL. For the most part, I use pkg.3, 4 and expert mode. I'll be honest with you though, when it comes to blending a rad on a ballnose, or corner radius endmill, I suck at it because frankly, we seldom do that sort of work in our shop so I never remeber the little tricks, but thats where cybergrinding comes into play, its easy to see what to do when you can over correct it by a mile to see what the outcome will be. Hell, I cant imagine running efficiantly without cybergrinding anymore, especially for something out of the norm, or tricky, which is why our older machines almost never get used for manufacturing anymore, mostly just regrinding on them.
As for Rolly, we like Rolly for small stuff, but so far I think the smallest tools I have done are around 1mm for some step drills, and some 2mm 3fl center cutting endmills. I wouldnt even atempt that on the Walters, not with the spindles in those machines, they are terrible.
How long have you been at it on the Walters?
