calculate the cutting speed based on the diameter of the workpiece to be processed and the number of revolutions of the workpiece

`S=[πDN]/100` m/min.

enter a value:

diameter of the workpiece to be turned (d):
in cm.
working revolutions/minute(n):

calculation result:

cutting speed(s):

calculate the number of revolutions based on the cutting speed and the diameter of the workpiece to be machined

`N=[100S]/[πD] r.p.m. `

enter a value:

cutting speed(s):
m/min.
diameter of the workpiece to be turned (d):
cm.

calculation result:

operation revolutions/minute (n):

calculate turn time

Time for Turning = (Length of the job to be turned) / (Feed/Rev).× r.p.m. min.

enter a value:

working hours:
metre
feed/speed:
working revolutions/minute:

calculation result:

turning time:

calculate cutting time

Time for Borning = (Length to be bored) / (Feed/Rev).× r.p.m.

enter a value:

drilling cuttings length:
feed/speed:
working revolutions/minute:

calculation result:

time required:

calculate drilling time

Time for Drilling = (Depth of hole to be produced) / (Feed/Rev).× r.p.m.

enter a value:

hole depth:
feed/speed:
working revolutions/minute:

calculation result:

time required for drilling:

calculate face milling time

Time required for Cut = (Length to Cut) / (Feed/Rev).× r.p.m.

enter a value:

cutting length:
supply:
working revolutions/minute:

where, Length of Cut = 1/2 (Dia. of job)

calculation result:

cutting time:

calculate knurling time

Time for Knurling = (Length of Cut) / (Feed/Rev).× r.p.m.

enter a value:

cutting length:
feed/speed:
working revolutions/minute:

calculation result:

time required for knurling:

calculate reaming time

Time for Reaming = (Depth of Hole) / (Feed/Rev).× r.p.m.

enter a value:

hole depth:
feed/speed:
working revolutions/minute:

calculation result:

time required for reaming:

calculate tapping time

Time for Tapping = `[L+D/2]/[P itch × r.p.m.] min. `
Time for Cutting = `[3/2(L+D/2)]/[P itch × r.p.m.] min. `

enter a value:

threaded part length:
use tap diameter:
tooth distance:
working revolutions/minute:

calculation result:

thread time required:
cutting time:
about lathes a lathe is a machine tool that mainly uses turning tools to turn rotating workpieces. drills, reamers, reamers, taps, dies and knurling tools can also be processed on lathes.
