ANSWERS /GRADED A+/VERIFIED/

bench grinder - ---Answers---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 - ---Answers---A single line of code in an NC part program

Bottom Height - ---Answers---The final machining height/depth and the lowest depth that the tool descends into the stock.

Build time - ---Answers---Length of time for the physical construction of a rapid prototype, excluding preparation and post-processing time. Also known as run time

CAD - ---Answers---Computer Aided Design. The use of computers in converting the initial idea for a product into a detailed engineering design.

CAM - ---Answers---Computer Aided Manufacturing. The use of computers in converting engineering designs into finished products.

Casting - ---Answers---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 - ---Answers---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 - ---Answers---Computer Integrated Manufacturing. A company-wide management philosophy for planning, integration, and implementation of automation.

Clearance fit - ---Answers---Limits the size of mating parts so that a clearance always results when mating parts are assembled.

Clearance Height - ---Answers---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 - ---Answers---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 - ---Answers---A system that uses feedback from the input to control the output.

CNC - ---Answers---Computer Numerical Control. A numerical control method in which one computer is linked with one machine tool to perform NC functions.

Code - ---Answers---A set of computer instructions to perform a given operation or solve a given problem.

Comment - ---Answers---A line of text in a computer program that is ignored by the computer. Comments are used to explain programs to humans.

Competent - ---Answers---Properly or sufficiently qualified; capable or efficient.

Concept Model - ---Answers---Physical model intended primarily for design review and not meant to be sufficiently accurate or durable for full functional or physical testing.

Conditioning Process - ---Answers---Process in which the properties of a material are changed using mechanical, thermal, or chemical means.

Control System - ---Answers---A system in which one or more outputs are forced to change in a desired manner as time progresses.
