Abstract
There are many causes for overheating, large stress, strain, deformation and fracture as well as tool
wears of metal cutting process. velocity, feed rate, depth of cut, type of material (work piece and
tool) and lubricant type takes the lion’s share those parameters:
This thesis deals the effect of metal cutting variables, depth of cut and cutting speed on temperature,
cutting forces, strain and von-misses stress and obtaining optimum conditions of cutting speed and
depth of cut using finite element method rather than experimental techniques which makes the
investigation very time consuming and expensive.
At this point, finite element modeling and simulation becomes main tool. For this purpose,
orthogonal milling simulation of AISI 1045 steel as work piece and un coated tungsten as tool are
performed and modeled.
The effects of cutting variables on cutting forces and thrust force also investigated by comparing
simulation results with experimental results available in the literature. Then, thermo- mechanical and
thermal analyses are performed using ANSYS software. Lastly, strain, temperature and stress
distributions are investigated[8].
Here metal cutting variables of velocity 1m/s,1,5m/s,2m/s,2.5m/s and 3m/s with depth of cut of
1mm,1.5mm,2mm considered and the resulting temperature,strain,stress and total deformation of
each condition is investigated. here at increasing parameters the resulting temperature is above
working service temperature and the material melts.
