Reviewer For Midterms: It it the conical part of the drill. Points Proper chucking of workpieces, use of safety guards. Lathe Safety The process of cutting metal in small pieces with a cold chisel Chipping and hammer It is the standard temperature to start the heating in automatic 1200℃ to 1300℃ hot forging This is commonly used drill press in many schools shops as well Standard Drill Press as many small drilling jobs The part that fits into the holding device Shank Heavy objects, Sharp edges, and Electrocutions are what type Material Handling of hazards? It is done to improve the crystalline structure of the steel. Normalizing The narrow section between the flutes is the backbone of a drill. Web The heating and then cooling of metal to make the metal less Annealing brittle, or more malleable and ductile. The narrow groove to determine the size of drill. Margin It is a cut on a machine and then carefully scrapped by hand. Surface Plate Have a motor driven flywheel that stores energy to drive a ram Mechanical Forging Press much lighter than a hammer through a crankorother mechanical device A square faced hammer used by smiths on which is possible to Set Hammer hit directly with hand hammer Increases the diameter of the work piece by compressing its length Upset Forging These are safety procedures designed to prevent accidental Lockout/ Tagout procedures machine start up during maintenance or repair. The excess metal squeezed out from the die cavities forming. Flash The rows of teeth crossing each other which give the sharp point Double Cut Usual size of a cold chisel 3/4” to 1” The groove of a drill it is carries out the chips and admits the coolant. Flute The kind of wood that the handle is made of Hickory A process is similar to kneading, where a slow continuous pressure Press Forging is applied to the area to be forged This machine is especially useful which is drilling holes in the Radial Drill Press large and heavier pieces. Use for handling picking works and for handling while forging Pick up Tongs It has a narrow cutting edge and use for cutting narrow grooves Cape Chisel Common sizes of files 8” to 12” A narrow rocket‐shaped tool provided with sharply beveled Hot Cutter cutting edge and used for striking with a sledge. It is used to measure the diameter of holes or to measure space. Inside Caliper A sharp pointed tool used to make small punch mark on layout line Prick Punch to make them last longer This involves selecting the right tools for the job, handling Safe use of tools and Equipment them correctly, maintaining themto ensureproperfunction and prevent damage. Proper Sawing Technique: When sawing, stand with one foot pointing toward the bench. The arch of the right foot should be about 12 inches from the heel of the left foot. Face the work, and keep your body at a 30‐degree angle to the sawing stroke. Move your arms slightly in addition to stepping forward and backward.
