Cutting force: formula
(OP)
Hi, I want to calculate the tangential cutting force Ft.
Can someone give me a good reference or the formulas?

RE: Cutting force: formula
You need to be more specific in terms of machining process and the material your cutting

RE: Cutting force: formula
See page 6,7 of this link for cutting for cutting forces:-

Are you sure you want the cutting force or do you want the speed and feeds etc for cutting your material, if the latter is the case then do a Google search.

RE: Cutting force: formula
torque= Fc X D(avg)/2
The torque you get from the power of your lathe depending on rpm of the chuck.
on page 7 Fc = cutting force
this is a copy of page 7:-
TABLE 22.3
N = Rotational speed of the workpiece, rpm
f = Feed, mm/rev or in/rev
v = Feed rate, or linear speed of the tool along workpiece length, mm/min or in/min
=fN
V = Surface speed of workpiece, m/min or ft/min
= π Do N (for maximum speed)
= π Davg N (for average speed)
l = Length of cut, mm or in.
Do = Original diameter of workpiece, mm or in.
Df = Final diameter of workpiece, mm or in.
Davg = Average diameter of workpiece, mm or in.
= (Do +Df ) /2
d = Depth of cut, mm or in.
= ( Do +Df ) /2
t = Cutting time, s or min
=l/f N
MRR = mm3/min or in3/min
= π Davg d fN
Torque = Nm or lb ft
= ( Fc )( Davg /2 )
Power = kW or hp
= (Torque) (w , where w=2π radians/min

RE: Cutting force: formula
Please re-read and explain your post, I cannot understand your point:-
"Three principle forces in turning" shouldn't that be "Three principal forces in turning"?
The two quotes above are the same.
RE: Cutting force: formula
principal
Not the same

Yes Chicopee I agree with you, however I won't be writing to the site to correct it.
