Reflection helps designers to learn from their experiences, to integrate and co-ordinate different aspects of a design situation, to judge the progress of the design process, to evaluate interactions with the design context, and to plan suitable future design activities.
Answer:
The shear plane angle and shear strain are 28.21° and 2.155 respectively.
Explanation:
(a)
Orthogonal cutting is the cutting process in which cutting direction or cutting velocity is perpendicular to the cutting edge of the part surface.
Given:
Rake angle is 12°.
Chip thickness before cut is 0.32 mm.
Chip thickness is 0.65 mm.
Calculation:
Step1
Chip reduction ratio is calculated as follows:


r = 0.4923
Step2
Shear angle is calculated as follows:

Here,
is shear plane angle, r is chip reduction ratio and
is rake angle.
Substitute all the values in the above equation as follows:




Thus, the shear plane angle is 28.21°.
(b)
Step3
Shears train is calculated as follows:


.
Thus, the shear strain rate is 2.155.
Answer:
5,4,1, this is a explication
Answer:
X_cp = c/2
Explanation:
We are given;
Chord = c
Angle of attack = α
p u (s) = c 1
p1(s)=c2,
and c2 > c1
First of all, we need to find the resultant normal force on the plate and the total moment about leading edge.
