  4. Re: Need advice on the calculations for cutting a semi-circle on the XZ axis

    Yes That's correct


    That line moves the cutter to start point

    I'm not sure if the arc is G02 or G03

    Suggest you try doing the arc in two moves. (see below)

    G01 X-0.0469 Z0.0469
  5. Re: Need advice on the calculations for cutting a semi-circle on the XZ axis

    What about this?
    Touch tool on top of plate and set as Z0.0469
    G01 X-0.0469 Z0.0469
    G01 Z0
    G18 G02 X0.0469 R0.0469
    G01 Z0.0469
    G00 Z1

    Re: 3-dimensional circular interpolation question

    Write you code for one plane eg G17 and Rotate using G68 (Fanuc)
    The hardest part is determining the second plane angle when setting the controller, if your arc's plane is rotated on two planes.

    Re: offset turning macro?

    Hi, unable to confirm your macro, but if I have the dimensions correct, I think??? the G03 X-#102 value should be -15.4 and the G03 X#104 should be 35.4
    Attached drawing as my understanding.

    Re: Cutting at angle

    Can you touch off cutter at different angles and note XYZ as per drawing.

    The number of lines of code is not the problem. Just sorting out the conversion.
