Abstract/Objective
The intent of this project is to analyze manufacturing processes with respect to project specific requirements such as accuracy, precision, cost, reliability, and safety.
Analysis
Design Calculation:
PD = (Number of Grooves) (Pitch)/Pi = 1.432″
OD = PD-2U = 1.432-2(.015) = 1.402”
Case -1
Assumption
1. All manufacturing operations will be performed by a casting process except the tapped holes.
2. All tapped holes to be machined.
3. List of drawing needed to manufacture the part:
a. Drawing for casting

b. Drawing for machining

Case -2
Assumption
1. All operations will be performed by machining process because of high precision and accuracy.
2. List of drawing needed to manufacture the part:
Drawing for machining

Detail machining process:
a. Facing
b. Turning OD

The timing belt pulley as shown in the next page is to be manufactured using multiple processes
as defined below:
Case- 1: Select an appropriate manufacturing process, where dimensional accuracy and precision
is not important for most of the part features. However, certain features such as tapped holes and
bore hole require precision. Assume the material is delrin.
Case – 2: Select an appropriate manufacturing process where dimension accuracy and precisions
are critical. Assume the material is aluminum alloy and the part is to be used for automotive
power transmission device. Produce a manufacturing drawing with a list of tools require to
manufacture the part.
