ABS - correct answer ✔Acrylonitrile Butadiene Styrene. A thermoplastic with
rubber added for high toughness.
absolute - correct answer ✔System in which positions are given with respect
to a fixed point, usually the origin.
Absolute Encoder - correct answer ✔An optical encoder that gives an exact
position even in the event of a power failure.
Accuracy - correct answer ✔The degree of closeness of measurements of a
quantity to the actual (or accepted) value.
Additive Process - correct answer ✔Fabrication of a part by adding material.
Address Character - correct answer ✔A letter used in G & M code
programming to designate a class of functions.
AGV - correct answer ✔A computer controlled system that uses pallets and
other interface equipment to transport work pieces to NC machine tools and
other equipment in a flexible manufacturing system
Ampere (A) - correct answer ✔SI unit for electric current
ASRS - correct answer ✔Automated Storage and Retrieval Systems. A
system that moves material either vertically or horizontally between a storage
compartment and a transfer station within a process
,Assembling - correct answer ✔The process of putting a product together out
of separate parts
Automation - correct answer ✔The use of technology to ease human labor or
extend the mental or physical capabilities of humans.
Axis - correct answer ✔A single linear direction used in the Cartesian
coordinate system to locate points in space.
bench grinder - correct answer ✔A grinding machine that has been mounted
to a bench or table. The grinding wheels mount directly into the motor shaft.
Normally one wheel is coarse, for roughing, and the other is fine, for finishing
Block - correct answer ✔A single line of code in an NC part program
Bottom Height - correct answer ✔The final machining height/depth and the
lowest depth that the tool descends into the stock.
Build time - correct answer ✔Length of time for the physical construction of a
rapid prototype, excluding preparation and post-processing time. Also known
as run time
CAD - correct answer ✔Computer Aided Design. The use of computers in
converting the initial idea for a product into a detailed engineering design.
CAM - correct answer ✔Computer Aided Manufacturing. The use of
computers in converting engineering designs into finished products.
, Casting - correct 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 - correct 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 - correct answer ✔Computer Integrated Manufacturing. A company-
wide management philosophy for planning, integration, and implementation of
automation.
Clearance fit - correct answer ✔Limits the size of mating parts so that a
clearance always results when mating parts are assembled.
Clearance Height - correct 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 - correct 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 - correct answer ✔A system that uses feedback from the input
to control the output.
CNC - correct answer ✔Computer Numerical Control. A numerical control
method in which one computer is linked with one machine tool to perform NC
functions.
