rt configuration and use v Identify the advantages and lim itations of broaching i BASIC PRINCIPLES OF BROACHINING Broaching is a machining process for remo val of a layer of ma terial of desired width and depth usually in one stroke by a slender rod. Calculate degree of statical indeterminacy of a planar truss 2 Analyse the indeterminate pla nar truss for external loads 3 Analyse the planar truss for temperature loads 4 Analyse the planar truss for ca mber and lack of fit of a member 101 Introdu The existence of some physical variabl es like force temperature etc and its magnitude or strength cannot be detected or quantified directly but can be so through their effects only For example a force which can neither be seen nor be gripped but ca 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 Its highproduction metalremoval process is sometimes required to make oneofaki nd parts The concept of broaching as a legitimate machining process can be traced back to the early 1850s Early broaching applications were cutting keyways in pulle ys an 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 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 rt configuration and use v Identify the advantages and lim itations of broaching i BASIC PRINCIPLES OF BROACHINING Broaching is a machining process for remo val of a layer of ma terial of desired width and depth usually in one stroke by a slender rod 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 Constructional Licensing in Morphology and Syntax b. we /us three- Version 2 ECE IIT, Kharagpur and claim it to be a multimedia presentation.
