The extra hours over what was quoted on this would go down as 'non conforming material' or something at my place and the customer would pay for it. The office cant quote for misalignment. We get castings that're all over the place, sometimes with a lot of excess in places it should be, turns a 60 hour job into 80 so that goes down as extra.

Tooltek finished", kzitem.info/news/bejne/qX2i3Hl_r5OAe44 Seems to me that trepanning is so "out of the line" of any regular machining shop that it's just not worth keeping the tools and all for once in a blue moon job - and that's why there were shops like Tooltek, doing only that. If you have jobs like this one here just hog out the material, charge the customer and that's it - till the next time.

Love to see David Wilks make the most insane difficult trepanning jobs 3 to 4 meters deep with in tight tolerances. His calm voice and special English accent. Some times the cutout material core from expensive materials can pay the trepanning tool price. There are some of the shelf tools for that diameter but properly not able to cut in that debt we could see here. I've used one of the shelf tool for material thickness of 60 mm from either Iscar or Sandvik.

You can work it out from initial dimensions of the workpieces and the finished items - density of steel is about 7.8-7.8 g/cm3, so when you substract the volume of finished piece from initial volume you can estimate it pretty close. Curtis from CEE asked his viewers, in the video in which he was making a toolpost for a lathe, what is the weight of the finished toolpost - and some people got it pretty much spot on.

Hi, im from the UK, its MM and Metres here now, big government push in 1970s to use the metric system, being a small country, we needed to export our machines, but didn't last very long. I fully understand why the USA has not completely adopted the Metric system, because it is such a large country, and the cost of converting or replacing machine tools would be to high. I was 8 years old when our schools started teaching metric, and we changed to 100 pennies in a pound (was 240), when i started my engineering apprenticeship in 1978, we used both systems, and on nearly always imperial/inchs calibration tools.
