    HEM and Dynamic Tool Paths

    Thanks jlw. It is a great tool, but my issue is I need to explain the difference between regular chip thinning and HEM. Does the HEM modify the radial step over, thus increasing the IPT? Inquiring minds want to know. thanks

    HEM and Dynamic Tool Paths

    Does anyone have the math that is used to calculate this? Example: I'm using a 3/8 4 flute at 20% step-over, with radial chip thinning my IPM is 86. when I use HEM, the IPM jumps to over 100 IMP, but I still have the 20% radial cut. Can someone give me the math behind this? Thanks in advance.

    thread milling question

    Normally thread mill should be run from the bottom to the top, but in hard mat'l it should run from top to bottom. Basically the first thread cuts and the others chase.

    Best Method for face machining

    Not necessarily, most face grooveing tools will create their own clearance. The initial penetration must be within the range of the tool, but normally there is no limitation after the initial plunge.

    Mastercam Dental

    I've looked into this also. My nephew and niece are both dentist. I've gone to some shows and they have some pretty neat tools to do this with. A complete setup with software and machine was about 100grand. The whole process would take around 45mins. This would include a digital scanner for the mouth. I didn't think I would be able to compete with the setup, plus you need to have an understanding of tooth margins. Let us know how it works out. Rob

    Okuma Multus B400 face groove (G72) errors

    What kind of face grooving tool are you using? Some face groove tools are above center height and this may effect the width.
