Basic formulas Turning (Cutting time) Cutting time (External turning case 1: 1 pass machining) At constant revolution T : Cutting time [sec] L L : Cutting length [mm] 60 x L T= f : Feed rate [mm/rev] fxn n : Spindle revolution [min-1] Dm At constant cutting speed Dm : Workpiece dia. [mm] 60 x π x L x Dm Vc : Cutting speed [m/min] T= 1,000 x f x Vc Cutting time (External turning case 2: multi-pass machining) T : Cutting time [sec] L At constant revolution L : Cutting length per pass [mm] ap : Depth of cut per pass [mm] 60 x L T= xN f : Feed rate [mm/rev] D2 D1 fxn n : Spindle revolution [min-1] At constant cutting speed D1 : Max. dia. of workpiece [mm] 60 x π x L x (D1 + D2) D2 : Min. dia. of workpiece [mm] T= xN 2 x 1,000 x f x Vc Vc : Cutting speed [m/min] N : Number of passes = (D1 - D2) / ap / 2 (if it is indivisible, obtain integer by rounding up one place of decimals.) Cutting time (Facing) T : Cutting time [sec] T1 : Cutting time before reaching L At constant revolution Max. spindle revolution [sec] 60 x (D1 - D2) L : Cutting length [mm] T= xN 2xfxn ap : Depth of cut per pass [mm] D2 D1 f : Feed rate [mm/rev] At constant cutting speed n : Spindle revolution [min-1 ] 60 x π x (D1 + D2) x (D1 - D2) D1 : Max. dia. of workpiece [mm] T1 = xN 4,000 x f x Vc D2 : Min. dia. of workpiece [mm] Vc : Cutting speed [m/min] N : Number of passes = L / ap (if it is indivisible, obtain integer by rounding up one place of decimals.) Cutting time (Grooving) T : Cutting time [sec] R T1 : Cutting time before reaching At constant revolution Max. spindle revolution [sec] 60 x (D1 - D2) L : Cutting length [mm] T= 2xfxn f : Feed rate [mm/rev] D2 D1 At constant cutting speed n : Spindle revolution [min-1] 60 x π x (D1 + D2) x (D1 - D2) D1 : Max. dia. of workpiece [mm] Technical information T1 = D2 : Min. dia. of workpiece [mm] 4,000 x f x Vc Vc : Cutting speed [m/min] Cutting time (Cut-off) T : Cutting time [sec] T1 : Cutting time before reaching At constant revolution Max. spindle revolution [sec] 60 x D1 T3 : Cutting time when reaching T= 2xfxn (D3) Max. spindle revolution [sec] At constant cutting speed f : Feed rate [mm/rev] D1 n : Spindle revolution [min-1] 60 x π x (D1 + D3) x (D1 - D3) T1 = nmax : Max. spindle revolution [min-1] 4,000 x f x Vc D1 : Max. dia. of workpiece [mm] 60 x D3 D3 : Diameter when reaching max. spindle revolution [mm] T3 = T 1 + 2 x f x nmax Vc : Cutting speed [m/min] R41
