    Determining single point diamond machining parameters for new material?

    Hi there, If I have a new material in my shop and I want to single point diamond turn it, obviously, I don't really want to go through the hassle of machining different diameters with different parameters, taking the workpiece to a laboratory and analysing the surface parameters. How do...

    Single Point Diamond Turning Cutting Force Analysis

    Hi there, I performed some SPDT of Si (111) and am looking to analyse the cutting force data obtained. Unfortunately, the force readings stopped midway through, and I had to reset the machine and restart the force measurements (see long blue line in attached image). I end up obtaining the...

    Slightly corroded VNA ports?

    The VNA I'm currently using has some oxidization/corrosion on the outer rim of the ports. I wonder if this will have an effect on measurements taken? (I have no idea how the corrosion happened) In my mind, the wavelength of frequencies is naturally much larger than the tiny pits caused by the...

    Tolerance feature interpretation? [updated, question added]

    Hi there, Can somebody please take the time to explain the relevance/correct interpretation of this tolerance feature? I'm not a mechanical engineer by training (electronic), so this is all a little new to me. The drawing declares general tolerance to ISO 2768-M. I'm specifically referring...
