1.) Construction Details and Operation of Different Parts of a Shaper Machine. (9:31 mins) https://www.youtube.com/watch?v=PmYkRpGsMto a) What are the function of the guideways?  The function of this is to guide the work table in a reciprocating movement up and down and the guideways above the column guides the ram of shaper machine in the reciprocating movement forward and backward. b) What is the function of elevating handwheel?  The function of this is used to elevate the work table upwards to downwards c) Where is the cutting tool mounted in a shaper machine?  It is mounted on the tool post just like the Lathe Machine 2.) 6 Different Types of Shaper Machine Operations | TheEngineersPost (7:13 mins) https://www.youtube.com/watch?v=qxBTSUtKl1M a) In machining vertical surfaces, how much is the downfeed (in terms of millimeter) given at the end of each return stroke?  The feed is about 0.25mm given at the end of each return stroke b) What is necessary on the work to prevent the cutting edge of the tool from wear due to dragging?  Lubrication c) In machining horizontal surfaces, why is it that the cutting edge should not be projected much below the tool holder?  The vertical slide of the tool head should not be made to overhang too far below the ram if otherwise, the tool will be weakened and subjected to under strain. Also, a lot of chatter will result. 3.) Big Cincinnati 36'' Shaper has Arrived! Walk around and testing. (20:08 mins) https://www.youtube.com/watch?v=I86XFZlje0c a) What cutting tool was used in the video?  Cincinnati Heavy Duty Shaper b) What was considered as the lifeblood of the machine?  The lifeblood of the machine is the hydraulic oil c) In moving the table to the left or right, one rotation of the crank will give how much movement for the table?  Every rotation is half of an inch d) What is the longest stroke of the machine?  36 e) How heavy and what are the dimensions (length & width of the machine)?  RAM is 11,000 pounds, 10 ft long, 4 ft wide
