Question

Basics - use of calculations, equations

Hi

In a turning operation, I would like to use a variable CUT_FEED which is currently 10. This value should depend on the workpiece diameter:

- when ØA then CUT_FEED B

- when ØA/2 then CUT_FEED B*2

Cheers

Bob

    hi,

    inside parameters open edit machining parameters->select cut_feed and you ave "d=" it is symbol for equation-open it and write:

    work_dia=workpiece_dia:4

    if work_dia>=10

    cut_feed=15

    else

    cut_feed=5

    endif

    where work_dia is a parameter to workpieces diameter.

    br,

      Hi Ionut

      I understand the logic around but I got some errors with 'workpiece diameter' parameter. The workpiece diameter should vary with STEP_DEPTH.

      work_dia=workpiece_dia:4

      error Invalid symbol 'workpiece_dia:4' found.

      if work_dia>=10

      error Invalid symbol 'work_dia' found.

      cut_feed=15

      else

      cut_feed=5

      endif

      Thanks.

      Hi,

      when you write work_dia = "you have to select the revolve, extrude , or the feature from workpiece, then it will appear the dimension and you select that dimension" - in my case the was workpiece_dia:4 but usually it will be d3:2 or d8:2 someting like that.
