Intro to Manufacturing Processes
Exam 1
This course will focus on which aspects(s) of the manufacturing sequence?
A. Design
B. Material Selection
C. Process selection and manufacture
D. Evaluation - Answer-C. Process selection and manufacture
Machining processes, such as lathe turning, drilling and milling, would be classified in this group of
manufacturing processes
A. Material removal
B. Casting
C. Deformation processing
D. Consolidation - Answer-A. Material Removal
The newest class of manufacturing processes produces products directly from computer files without
part-specific tooling, molds, dies, or fixtures. One-of-a-kind products or small quantities can be made in
relatively short time.
True or False - Answer-True
Consolidation processes:
A. Exploit the ductility or plasticity of certain engineering materials
,B. Are based on the principle that a liquid will assume the shape of its container
C. Start with an oversized piece of material and remove unwanted segments
D. Build a desired shape by joining two or more segments - Answer-D. Build a desired shape by joining
two or more segments
Which of the following is NOT a true statement about the casting process?
A. Casting is an attractive means of producing complex shapes
B. Cast products must be entirely solid. They cannot contain hollow sections or internal cavities
C. Casting can produce desired shapes from just about any material that can be melted
D. Cast products can range in size from a fraction of an ounce to several tons - Answer-B. Cast products
must be entirely solid. They cannot contain hollow sections or internal cavities
The 2 major groups of casting processes are:
A. Expendable mold and multiple-use mold
B. Simple shape and complex shape
C. Metal and nonmetal - Answer-A. Expendable mold and multiple-use mold
The top segment of a mold, pattern, or flask - Answer-Cope
The horizontal portion of a gating system that channels molten metal from the sprue to the gates -
Answer-Runner
These features may be incorporated into a gating system to help prevent contaminated metal from
entering the mold cavity - Answer-Runner extensions and wells
This solid shape is inserted into a mold to produce a hole or internal cavity - Answer-Core
, The mold cavity is often formed by packing mold material around this shaped block that resembles the
part to be produced - Answer-Pattern
This additional reservoir of liquid metal is positioned inside a mold to compensate for solidification
shrikage - Answer-Riser
This open sleeve or band surrounds the upper and lower segments of a mold - Answer-Flask
This vertical portion of a gating system conducts metal down to the mold cavity - Answer-Sprue
The shaped void within a mold that fills with molten metal and ultimately produces the cast product -
Answer-Mold cavity
The total plumbing system that conveys liquid metal from the outside of the mold to the mold cavity -
Answer-Gating system
This part of the gating system first receives the stream of molten metal - Answer-Pouring cup
These projections on a pattern create additional cavities in a mold that are used to locate and anchor
cores. Both the projections and the created cavities are called_____. - Answer-Core print
This segment of the gating system has the smallest cross-section area and controls the flow of molten
metal - Answer-Choke
These small opening connect runners to mold cavities - Answer-Gate
The bottom half of a mold, pattern or flask - Answer-Drag
