(Lecture 05) Casting complete course- saking and distortion allowance

follow me on unacademy with ID- rohitguptaiit


Casting complete course for Gate ME and PI (playlist)


this is the 5th lecture of casting in the complete detailed GATE and production and industrial engineering course. in that lecture we pattern design. in which allowance we learn. in casting allowance are 5 type- shrinkage or contraction allowance, draft or taper allowance, machining or finishing allowance, rapping allowance, distortion allowance. shrinkage allowance we cover in last lecture. in that particular lecture we cover detailed machining allowance and distortion allowance.Casting lec 05 this lecture is about saking allowance and distortion allowance.

This topic is very important in GATE and ESE exam if your stream is mechanical (ME) or production and industrial engineering (PI). here we provide full detailed course of each topic that can get more impact on GATE and ESE exam.

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.

In this video, I've discussed about the Gating system used in Casting.
I've explained the Gating system with the help of :-
1) Pouring basin/Cup.
2) Sprue
3) cope and drag
4) Sprue base or well
5) Runner
6) Skim Bob
7) Choke
8) Gates and its types viz.
Top, bottom and parting gate (also known as ingates)
9)mold or mould
10) Riser with types.
I've also discussed about Chvorinov's rule and Canie's method that are used to calculate solidification time and freezing ratio respectively.
The language used for explanation is Hindi or Urdu and the presentation is made in English language.
