IME 146 Final Study Guide Questions with Verified Solutions

IME 146 Final Study Guide Questions with Verified Solutions Prior to the creation of CNC machines, drilling holes in material was done by: Handheld manual drilling braces with auger bits With the use of electric, handheld drills, the operator still controls the quality of the hole being drilled. True A common name used for the manual milling machines is: Bridgeport milling machine A manual milling machine is different from a drill press, because it has handles that move the table side to side and up and down? True On the manual milling machine, one of the primary cutting tools is: An endmill On a manual milling machine, the operator does not need to be precise with the handle movements to control the distance and the depth of each cut? False The CNC machine was created to provide accurate production parts. What does CNC stand for? Computer Numerical Control On CNC equipment, the machine is following a program that tells the machine what to do. True One of the most popular machines that Haas builds today is: VF-2 The CNC machine allows modern manufacturing to make essentially identical parts repeatedly. This concept is known as Component or Part Interchangeability True An important element of a CNC machine is that the parts made today, will be identical to the parts made yesterday, for any one program being run in the machine. True When the part being made is going to be rectangular in shape, the shape of the raw material from which the part will be made most likely is? Rectangular stock It is not important to do a quick check on the raw material for basic shape and overall size to make sure the material is correct. False When we say the machine is "set up," we mean: The machine is prepared to make a particular part Once the machine is set up, and the machine knows where the vise, tools, and workpiece are, we need a _________________ to get started. A CNC program to be loaded into the machine to tell the machine what to do When it is time to get started running parts, which four items are best matched to the correct steps? Load the raw material, keep it square, reference the part stop, and tighten the vise It is very important that the operator watch the first part being machined. True If the operator hears a strange noise coming from the machine, it is recommended to: Press Feed Hold and get the Supervisor There are a variety of cutting tools used in a CNC machine. The function of the face mill is? To make the top of the workpiece very flat, and prepare it for additional machining Another popular cutting tool for CNC machining is the end mill. The primary function of an end mill is for profiling a part, or creating pockets in a part. True Two more cutting tools that the machinist commonly uses are the drill and the tap. These tools often work in combination, first to drill the holes,
