Base: It is the main body of the machine. The oil under high pressure is drawn from the reservoir. Samuel Bentham was a talented English engineer and a world-famous naval architect. The base provides support for all other machining tools. This motion of the cutting tool is achieved by the “Quick Return Mechanism”. (a). In the gear type shaper machine, ram is reciprocating in motion. The one thing that is very important in the case of the Whitworth quick return mechanism is the time. As the pump is a constant discharge one, within a fixed period, the same amount of oil will be a pump into the right or to the left-hand side of the cylinder. a) rotary, reciprocating b) reciprocating, rotary c) rotary, rotary d) none of the mentioned View Answer The shaper ram also can be driven in this manner, but many times a quick-return link mechanism is used. The feed motion follows the “Pawl and Ratchet Mechanism”. Based on the type of Driving Mechanism A single point cutting tool has only one cutting edge. Though some skills are required to operate it, people with some experience with the machine can handle it without any hassle. Irregularly shaped holes having the tight corners cannot be made using the milling or any other machining process. This mechanism is called slotted lever quick return mechanism and it drives a horizontal ram which reciprocates in the guide ways provided on the top surface of the machine frame. Beam engine (b). The cutting speed is adjusted with the help of the throttle valve. Crank and Slotted Link Mechanism. Following are the different types of shaper machines. - Shaper machine is operated by quick return mechanism. Shown in the figure. The sliding block which is mounted upon the crankpin is fitted within the slotted link. These directions can be used for giving the feed. Cutting action in the forward stroke of the ram is caused by the tool head present in the clapper box. The workpiece can be moved in any given direction.
