1. A method for setting a depth of cut in an initial axial direction for a rotating cutting tool and operating the tool accordingly, comprising:
when a tool T is mounted on a spindle S, receiving, an overhang length L of the tool T, a diameter D of the tool T, an overhang length ratio reference value C, and an axial depth of cut reference value E; calculating an axial depth of cut Y by Equations 1, 2, 3, and 4,
wherein Equation 1 isA=LD A: Overhang length ratioL: Overhang lengthD: Tool diameter,wherein Equation 2 isB=CA B: Ratio of overhang length to reference valueA: Overhang length ratioC: Overhang length ratio reference value,wherein Equation 3 is
κ=B−3 κ: Rigidity weightB: Ratio of overhang length to reference value, andwherein Equation 4 is
Y=E×κY: Axial depth of cutκ: Rigidity weightE: Axial depth of cut reference value (15); setting the axial depth of cut Y as an initial axial depth of cut of a cutting process; and initiating the cutting process at the initial axial depth.
