Calculating tangential cutting force

Tangential cutting force for aluminum.

F_t = σ × A × Z_c × E_f × T_f

• Ultimate tensile strength (σ) = 310mpa

• Cross-sectional area of the uncut chip (A) =  2*0.0762 = 0.1524mm

• Number of teeth engaged with a workpiece (Z_c) 3/(360/180)=1.5

• Engagement factor of a workpiece material (E_f) = 1.1 from previous post and website link

• Cutting tool wear factor (T_f) = 1.1 from table on web page.

 F_t = 310 * 0.1524 * 1.5 * 1.1 * 1.1  = 86 N 2SF

 

Tangential cutting force for MDF.

F_t = σ × A × Z_c × E_f × T_f

• Ultimate tensile strength (σ) = 18mpa

• Cross-sectional area of the uncut chip (A) =  3.125*0.2 = 0.625mm

• Number of teeth engaged with a workpiece (Z_c) 2/(360/180)=1

• Engagement factor of a workpiece material (E_f) = 1.1 from previous post and website link

• Cutting tool wear factor (T_f) = 1.2 from table on web page.

 F_t = 18 * 0.625 * 1 * 1.1 * 1.2  = 15 N 2SF
