Types of brakes Brakes are devices that dissipate ki netic energy of the moving parts of a machine In mechanical brakes the di ssipation is achieved through sliding friction between a stationary object and a rotating part Depending upon the directio. i Need and purpose of chipbreaking Continuous machining like turning of ductile metals unlike brittle metals like grey cast iron produce continuous chips whic h leads to their handling and disposal problems The problems becom e acute when ductile bu Define quantization 2 Distinguish between scala r and vector quantization 3 Define quantization error and optim um scalar quantizer design criteria 4 Design a LloydMax quantizer 5 Distinguish between unifo rm and nonuniform quantization 6 Define rat Describe the basic mechanism of material removal in USM ii Identify the proce ss parameters of USM iii Identify the machining characteristics of USM iv Analyse the effect of process par ameters on material removal rate MRR v Develop mathematical mod They belong to mechanical group of nonconventional processes like Ultrasonic Machining USM and Abrasive Jet Machining A JM In these processes WJM and AJWM the mechanical energy of wa ter and abrasive phases are used to achieve material removal or ma iv illustrate and deduce effective rake angle v state the e ffects of oblique cutting i Orthogonal and oblique cutting It is appears from the diagram in Fig 61 that while turning ductile material by a sharp tool the continuous chip would fl ow over 87 087 Version 2 CE IIT Kharagpur brPage 10br 0 870 sty bd Af 0 0 870 Af sty 087 yst fAz V bd Version 2 CE IIT Kharagpur brPage 11br a Bars in tension c l 26221 of IS 456 b Bars in compression c l 26222 of IS 456 Version 2 CE IIT Kharagpur brPage 12b Analyse hingeless arch by the method of least work 2 Analyse the fixedfixed arch by the elasticcentre method 3 Compute reactions and stresses in hingeless arch due to temperature change 341 Introduction As stated in the previous lesson tw ohinged an iv Classify chips and identify t he condition for different chip forms i Mechanism of chip formation in machining Machining is a semifinishing or finishi ng process essentially done to impart required or stipulated dimensional and form accuracy and The need for structures of a canal irri gation system for convey ing water from one point to another 2 Structures for conveying water ac ross over or under natural streams 3 Transitions in canals at change of cross section 380 Introduction A canal c Procedure for designing a screwbolted joint in eccentric loading Procedure for designing riveted joint under eccentric loading In many applications a machine member is subjected to load such that a bending moment is developed in addition to direct n Lesson 16 DMA 16(III) 8237 DMA Controller 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21A7 A6 A5 EOP A3 A1 A0 DB0 DB1 DB3 DB4 DACK1 Version 2 ME, IIT Kharagpur Lesson 4 Simple stresses Version 2 ME, IIT Kharagpur Lesson Simple stresses Version 2 ME, IIT Kharagpur Lesson Simple stresses Version 2 ME, I Version 2 ME, IIT Kharagpur Lesson 4 Compound stresses in machine parts Version 2 ME, IIT Kharagpur PA MyI VQIt Elements of force system at a beam section.
