Casting complete course for Gate ME and PI (playlist)
   • Casting complete course for Gate ME and PI  

This video is related to the chock area , gating ratio and some numericals related to gating ratio.

first we are targeting to finish the syllabus mention below then further go for next one-
Gate 2020 Production and industrial engineering (PI) syllabus for casting-
Section 3: Manufacturing Processes I
Casting: types of casting processes and applications; patterns – types and
materials; allowances; moulds and cores – materials, making, and testing; casting
techniques of cast iron, steels and nonferrous metals and alloys; analysis
of solidification and microstructure development; design of gating and riser; origin of
defects.

Joining of materials: Principles of fusion welding processes(manual metal arc, MIG,
TIG, plasma arc, submerged arc welding processes)–different heat sources (flame,
arc, resistive, laser, electron beam), and heat transfer and associated losses, flux
application, feeding of filler rod; Principles of solid state welding processes (friction,
explosive welding, ultrasonic welding processes); Principles of adhesive, brazing and
soldering processes; Origins of welding defects.

Machine Tools and Machining: Basic machine tools like centre lathe, milling
machine, and drilling machine – construction and kinematics; machining processes
turning, taper turning, thread cutting, drilling, boring, milling, gear cutting, thread
production, grinding; geometry of single point cutting tools, chip formation, cutting
forces, specific cutting energy and power requirements, Merchant’s analysis; basis
of selection of machining parameters; tool materials, tool wear and tool life,
economics of machining, thermal aspects of machining, cutting fluids,
machinability; Jigs and fixtures – principles, applications, and design

Non-traditional Manufacturing: Principles, applications, effect of process
parameters on MRR and product quality of non-traditional machining processes –
USM, AJM, WJM, AWJM, EDM and Wire cut EDM, LBM, EBM, PAM, CHM, ECM.

Metal Forming: Stress-strain relations in elastic and plastic deformation; concept of
flow stress; hot and cold working – forging, rolling, extrusion and wire drawing; sheet
metal working processes – blanking, bending and deep drawing; ideal work and
slab analysis;origin of metal working defects.


Section 4: Materials, Manufacturing and Industrial Engineering
Gate 2020 mechanical (ME) syllabus for casting-
Casting, Forming and Joining Processes: Different types of castings, design of
patterns, moulds and cores; solidification and cooling; riser and gating design.
Plastic deformation and yield criteria; fundamentals of hot and cold working
processes; load estimation for bulk (forging, rolling, extrusion, drawing) and sheet
(shearing, deep drawing, bending) metal forming processes; principles of powder
metallurgy. Principles of welding, brazing, soldering and adhesive bonding.


we are preparing full detailed GATE and ESE course for mechanical and production and industrial engineering course. learn hub is the new education channel having aim to provide free full detailed course in all categories. so please help us to fulfill that dream.
support us as you can.
thanks
तो आपको ये video कैसी लगी। हमे comments करके जरूर बताये। अगर video अच्छी और informative लगी हो तो Like करें, वरना dislike करें। aur किसी भी exam और job से related information के लिए हमारे channel को subscribe करें।

साथ में हम लोग सभी government exam की preparation के लिए crash course, full course classes start करने वाले है। उसके लिए आप लोगो की एक help की जरूरत है। help ये की आप लोग इस channel को dost से share करो, उनसे channel subscribe कराये। nice response होने पर
ये courses की class free में start ho जाएँगी।
So जुड़ें रहिये और जड़वाते रहिये।
