SolidWork

what is solidworks ? SolidWorks is a popular 3D computer-aided design (CAD) software that is used for creating and designing complex models and assemblies in mechanical engineering, product design, and other industries. It is developed by Dassault Systèmes, a French software company that also owns other popular software such as CATIA and SIMULIA. SolidWorks provides a range of tools and features for creating 3D models, such as sketching, surface modeling, solid modeling, sheet metal design, and assembly modeling. It allows users to simulate and analyze the performance of their designs before manufacturing, including motion analysis, finite element analysis (FEA), and computational fluid dynamics (CFD). It also supports collaboration and sharing of designs with other users through various formats such as STEP, IGES, and STL. SolidWorks is known for its user-friendly interface and intuitive design, which makes it easy for beginners to learn and use. It is widely used in industries such a

Welding : Production

Welding or Metal Joining Process : Joining Process : In mechanical bending , stength of the joint is less than combined strength of the original member . Classification of Joining Process : 1. Autogenous : - no filler material is added during joining . 2. Homogeneous : - filler material is used same as parent material . 3. Heterogeneous :  - filler material is used different from parent material . Welding :  Welding is the process of joining two or more similar or dissimilar metals - (A) with or without the application of heat . (B) with or without the application of pressure .

Type of Flame : Welding

Welding : Types of flame : The different of flame can be produced by varrying the oxygen , acceteteyne ratio . 1. Neutral flame 2. Oxidizing flame 3. Carburizing flame  Neutral Flame : The ratio of oxygen and aceteyne is equal to 1:1 .  The inner core will be yellow or red and outer cone will be light blue colour . The maximum temperature of neutral flame is 3100° that is inner core . Outer core temperature is 1275° . N is the size of inner core .       • The neutral flame is used to joining and cutting of all metals . Oxydizing Flame : The ratio of oxygen and acetelyne is equal to 1.15 to  1.5 that is greater than 1 The maximum temperature of oxydizing Flame is 3300 ° that is inner core. Outer temperature is 1350 °. In oxidizing flame exess amount of oxygen is present . Size of inner core is N/3 to N/2 . Oxydizing Flame is used to joining of high reactivd metals.like AL , Mg . Carburizing Flame : The ratio of oxygen and acetelyne is equal to 0.85 to 0.95 that is less than 1 . The maxi

Metal Casting : Production

  Metal Casting : Casting is a process in which the liquid molt en metal is poured into the casting cavity whose shape is same as that of the casting to be produced and allowed it to solidify . After Solidification the casting can be taken out by breaking the mould .                              Metal Casting Advantages of casting : 1. Any shape can be produced . 2. Any material can be cast . 3. Requiring tools are simple and inexpensive . 4. Heavy equipment can be cast easily in required size rather than fabricating them by joining several smaller pieces . Limitations Dimension accuracy and surface finish is poor . Steps in casting : 1. Pattern Making 2. Mould and core making 3. Pouring and solidification 4. Fetting 5. Inspection 1. Pattern Making : Patten is the replica of casting . Pattern size =casting size + - allowance Allowances : 1. Shrinkage Allowance ( SA) 2. Machining Allowance 3. Draft Allowance 4. Shake Allowance 5. Distortion Allowance / Bending Allowance Shrinkage Allowa
