LATEST 2025-2026 EXAM UPDATE |GRADE A+
GUARANTEE
CAD - Answer-Computer Aided Design. The use of computers in
converting the initial idea for a product into a detailed engineering
design.
CAM - Answer-Computer Aided Manufacturing. The use of computers
in converting engineering designs into finished products.
Casting - Answer-The process in which a solid material is made into a
liquid, poured into a mold, and allowed to harden in the shape of the
mold
Ceramics - Answer-Any of various hard, brittle, heat-resistant, and
corrosion-resistant materials made by shaping and then firing a
nonmetallic mineral, such as clay, at a high temperature.
CIM - Answer-Computer Integrated Manufacturing. A company-wide
management philosophy for planning, integration, and implementation
of automation.
Clearance fit - Answer-Limits the size of mating parts so that a
clearance always results when mating parts are assembled.
, Clearance Height - Answer-The first height the tool rapids to on its way
to the start of the tool path. is the z-axis plane above which no stock is
expected. The Retract height sets the height that the tool moves up to
before the next cutting pass.
Climb Milling - Answer-The milling tool advances through the material
so that the cutting flutes engage the material at maximum thickness and
then decrease to zero thickness.
Closed Loop - Answer-A system that uses feedback from the input to
control the output.
CNC - Answer-Computer Numerical Control. A numerical control
method in which one computer is linked with one machine tool to
perform NC functions.
Code - Answer-A set of computer instructions to perform a given
operation or solve a given problem.
Comment - Answer-A line of text in a computer program that is ignored
by the computer. Comments are used to explain programs to humans.
Competent - Answer-Properly or sufficiently qualified; capable or
efficient.
, Concept Model - Answer-Physical model intended primarily for design
review and not meant to be sufficiently accurate or durable for full
functional or physical testing.
Conditioning Process - Answer-Process in which the properties of a
material are changed using mechanical, thermal, or chemical means.
Control System - Answer-A system in which one or more outputs are
forced to change in a desired manner as time progresses.
Conventional Milling - Answer-The milling tool advances through the
material so that the cutting flutes engage the material at zero thickness
and increase to the maximum thickness.
Debug - Answer-The process of detecting and eliminating a device's
malfunctions.
Decision Block - Answer-The diamond-shaped block used for YES/NO
questions. These blocks have two outputs: 1 (for yes) and 2 (for no).
Declare - Answer-The process of letting a program know that you plan
to use a variable, what you want to call it, and how big it is
Defective - Answer-Imperfect in form or function.
