    Ok, so I'm average on Vectric Aspire and SheetCam but want to learn basics in F360 - i like the assembly stuff and 360 aspect of design that the other apps lack.

    Have watch a few videos but find the best way to learn is to pick something representative of a project either past or future and try designing it.

    Here we go, not to any scale and only the first steps of the part.

    I drew the stock, added two circles and then the slot on one.

    Doing the cam and a simulation it wants to cut round the whole part - presumably because it is following the path through the slot.

    Say i wanted to mill the holes out then do the outside then add the slot, what process should i be following?

    Would the slot be a separate setup or separate file/code etc?

    Apologies for basic questions but searching for this would probably take a long time ;)

    Several hours of the 'tube later ;) i have found an answer - draw another circle on the top plane and machine that instead of the actual hole - simples.

    Ok, so its been a quiet day in the day-job today but couldn't sneak home to work on the project as it was my watch as they say

    Been playing with Fusion360 Sort of come up with a plan for the top plate of my dual-spindle adaptor for the mill. My thoughts are in the machining process...

    Steps...
    Spot the three holes in the middle,
    Drill them through,
    Counter-bore them,
    Rough pocket out the two big holes,
    Finish pass on them,

    Questions so far,

    should i rough the holes then finish with a mill tool or should I go for the boring head and bore-gauges/caliper ??
    I was thinking to then flip over in the vise, mill the slot on the rear face, then flip back, bolt to table on scrap pads through the big holes and do the outer contour followed by the two small slots and a chamfer pass?
    How to chamfer the rear face once contoured?

    So far its been a blast, love the 360deg view

    Sorry I can`t be of more help mate, I`m still just getting to grips with F360 as well ! You seem to be making good progress though for the short time you`ve been using it

    Depends if you are making out of an oversized block or plate that is already at the correct thickness.

    If using plate I would use a another piece of plate underneath as a fixture, clamp at both ends then....

    Mill slot and drill holes(making sure to drill into plate below,
    Interpolate two large bores with a slot drill and chamfer
    Use a T shaped clamp in both bores to hold while milling the profile.

    Then put a couple of pins or drills in the holes and use them to align the part when you flip it over.
    Clamp with T clamps again.

    Counterbore and mill the two slots that break into bores.

    Thanks, not thought about a fixture below with the alignment holes :)

    I was going to use precision tooling plate, used it before and accuracy has been good on thickness.

    What about bore finish - mill outright or mill rough and boring head? Its a consideration because of the massively different clamping methods needed for a using a boring head.

    I don't think ultimate precision is needed, i was allowing +0.25mm clearance on bores, maybe more?
