morethereOct 29, 2010 · for end mills i think the default stepover is 40%. reading through the vectric forum and i've been using 20-30% as my start point. particularly for pockets/flat bottoms. for ball nose 3d carving i use 8% stepover - again from reading vectric forum and talking with folks at the last vectric user group meeting in memphis.
morethereStepover is the distance the cutter moves over when finish machining. for a smooth high quality surface the stepover should typically be less than 20% of the diameter of the cutter. the larger the stepover the faster the job will be machined, but the rougher the surface finish will be.

morethereAug 29, 2019 · adaptive milling is new in nx 12 for manufacturing and gives a nice cut pattern that gradually adapts to the shape of a cut region with smooth, flowing motions. unlike traditional cut patterns, adaptive milling doesn't violate the stepover input from one cut to the next. this makes it ideal for high speed machining.

morethereDec 15, 2011 · i'm just wondering what everybody prefers to use when 3d milling with ball mills. my dealer tells me that old school people use step over by distance while new school programmers use the scallop height. well, i guess i'm old school. i've always used step over by distance. i'm finishing a race track shape with a 1/8" ball.
morethereThis is because ball end mills must be used with very small stepovers in order to reduce the size of cusps in the material. compensating for this staircase effect and achieving the desired surface finish requires a proportionally small stepover or stepdown, typically 3 to 5 percent of the tool’s diameter.
morethereStepover. basic- all things being equal, this is the amount of material your tool encounters in percentage of the tool diameter. the lower the percentage the lower the force on the machine, the more accurate the cut. expanded-a good thing to know is most flutes are not 50% of the diameter of the bit, usually less.
