In industrial practice, the production of parts must be conducted with acceptable surface quality, as well as increased dimensional accuracy and short machining time. For the creation of flat surfaces, face milling is a widely accepted method due to the possibility of achieving both high productivity and accuracy. In the present work, the correlation between process parameters and cutting forces is attempted for face milling, through a series of experiments. Experimental work is carried out based on Design of Experiments (DoE) methodology. The results are analyzed by statistical analysis tools and regression formulas correlating forces with process parameters are derived. Determination of optimum process parameters is also conducted with a view to increase process efficiency.
