Answer: seen in the explanations
Step-by-step explanation:
Since no values for this problem is given, I will just give the formulas to solve the problem in mechanics of orthogonal plane cutting.
a) shear plane angle will be calculated using:
tan ϕ = r Cos α / 1- r sin α
Where :
r= chip thickness ratio
α = rake angle
ϕ = shear angle.
B) chip thickness
To get the chip thickness, we must calculate the chip thickness ratio using the formula:
Rt = Lc/ L
Where:
Lc = length of chip formed
L= uncut chip length.
Use the answer to solve for chip thickness with the formula;
Tc = t/ Rt
Where :
t = depth of cut
Rt = chip thickness ratio
C) shear strain for the operation will be solved using;
ε = cot β• + tan β•
Where:
ε = shear strain
β• = orthogonal shear angle.
