 Hello everyone, myself Professor Prithish Chitte, working in Mechanical Engineering Department in Valtian Institute of Technology, Sallapur. So this is the first session regarding the course CADCAM CE. Today we will discuss introduction to CADCAM CE, the learning outcomes. So at the end of the session, the students will be able to apply CAD fundamentals as well as advanced manufacturing technology to industry problems. CAD fundamentals means computer-aided design fundamentals. Also it consists of CAM and CA that is computer-aided manufacturing and computer-aided engineering. So today we will discuss the introductory part of computer-aided design, computer-aided engineering and computer-aided manufacturing. These are the three we can call as the parts of the course that is CADCAM CE. So first we will discuss our first concept that is computer-aided design. So computer-aided design which is the part of the course CADCAM CE which is concerned with the computer assistance. In earlier days the design has to be developed manually and maybe it will take time and whenever we are developing some design with respect to the manual thing, yes, there may be the chances of errors or mistakes due to the manual work. But here the computer-aided design consists of the use of the computers which is very important. There will be the use of the computers to fulfill the different functions. What are the different functions like? First of all there will be the creation, we have to create a design. We have to create a 3D model, maybe we have to create a computer-aided drafting sheet. If suppose there is a requirement of the modification, yes, if suppose if we are comparing the manual design and the computer-aided design, in the manual design modification is we can call it as very hectic part. So in the computer-aided design we can modify, we can edit the design because of the use of the softwares. There are the different types of softwares that will be used in the computer-aided design. Also there will be the part of analyze or maybe the analysis. In the computer-aided design it is calling as computer-aided engineering or engineering analysis. So whenever there will be the term design, so it consists of creation of the 3D modeling and the analysis. After that we have to optimize the design. What is meant by optimize or the optimization process? Validating the creation of the 3D model and the engineering analysis of the particular mechanical component. So these are the various functions which are with respect to the computer-aided design. The name itself that is computer-aided means of course there will be the assistance of the computer for the computer-aided design. Now there are the different types of we can call as functions or the concepts which are present in the computer-aided design. For example it consists of maybe the geometrical modeling. In the simple world we can also call as 3D modeling of any mechanical component. For example 3D modeling of a fuel injector or maybe the turbine blades. These are some of the applications in the 3D modeling of any mechanical component. Computer graphics. Computer graphics is a heart of the computer-aided design. Without the computer graphics or maybe the interactive computer graphics the computer-aided design concept is impossible, really impossible. It also consists of hardware and software. Yes, with respect to my statement that always 3D modeling can be done with respect to a software. Also it requires the hardware. Yes means there will be the use of combination of hardware and software in case of computer-aided design. And here there will be the replacement of the manual design by the use of the computers and the use of the different types of software in the field that is computer-aided design. Because there is a particular section or maybe the department in any manufacturing industry like a design department and that design department or the design engineer always be working on the different computer-aided designing softwares or maybe the machine softwares or maybe the engineering analysis softwares. Now I will show you the different we can call as the applications in case of computer-aided design. Yes in front of you there is a model with the simulation of we can call as the bevel gear the machine of the bevel gear. You can see the bevel gear is rotating both the bevel gears are rotating and there is a we can call as a machine is also provided. This is a shaft, this is a horizontal shaft that is provided to this particular bevel gear and this is a vertical shaft which is provided to particular this bevel gear and whenever we want to provide the animation or maybe the simulation in the Katya software this particular 3D modeling has been done with the help of Katya software and we have to provide the constraint we have to fix particular component with the help of which we can provide the simulation to the particular mechanical components. Yes the bevel gear is a type of gear which is a mechanical component whenever we will fix the particular shaft which is connected to the gears yes after that after constraining or yes after fixing the particular shaft we can have the simulation or the rotation or maybe the motion to the bevel gears yes there is one more application that is in front of you that is the application of maybe the linkage or maybe we can call it as the this is a link or maybe the mechanism the there are the two ways which are rotating with the help of link the particular behind there is a bar which is stationary yes in the kinematics of theory of machines these types of links and the mechanisms you can observe and with the help of a 3D modeling softwares like maybe the Katya software or maybe the solid work softwares yes we can have the simulation of the different mechanical components after that there is a second concept which is called as computer edit manufacturing now suppose I want to provide the sequence regarding these three terms that is CAD, CAM and CE so first of all there will be the computer edit design after that whenever I will create the 3D model of any mechanical component yes there will be we can call it as a computer edit design of maybe any mechanical component after that that particular 3D model have to be provided to the computer edit engineering section there will be the engineering analysis so whenever we will validate the 3D model and the engineering analysis of any mechanical component we can go to the computer edit manufacturing section now we will discuss computer edit manufacturing part now here also there is a term which is called as computer edit that is there will be the assistance of the computer or the use of the computer to fulfill the different functions regarding the manufacturing regarding the manufacturing so what are the different functions or the areas which consist of the computer edit manufacturing definitely there will be the part of automation yes now there is a assistance of the computer means there will not be any we can call as the conventional machine tools for example maybe we can call as the conventional lathe machine or maybe we can call as the conventional drilling machine or maybe the milling machine we are not using it inside the industrial automation so in the industrial automation the machine tools like maybe the CNC lathe machine CNC milling machines will be used for the higher rate of production or maybe to achieve the greater productivity in the manufacturing sector also there will be the use of planning I will call as that is the computer edit process planning after that there will be the computer edit controlling and of course there will be computer edit manufacturing also it consists of the different areas or the we can called as the sections or the sectors like industrial automation always there will be the requirement or the prerequisite of the computer edit design because that design data will have to be provided to the computer edit manufacturing now there will be the use of maybe the computer edit manufacturing CNC machine tools computer edit process planning and also there will be the use of hardware and softwares hardware and softwares now there are different types of applications regarding the computer edit manufacturing yes this is a particular software which is called as Autodesk Inventor where you can see the tool path you can observe this is the particular end mill cutter with the help of which we can have the we can call as a simulation or the cutting removal or with the metal removal process yes with respect to the g-code and m-code prerequisite will be for example the 3d model that we have to provide it to the particular computer edit manufacturing software and this is the output with the help of which this is the output with the help of which we can have the computer edit manufacturing concept so this is also one of the application regarding the computer edit manufacturing so this is the we can call as the CNC lathe operation this is the a tool bit this is the work with cylindrical work piece which will be fixed inside the headstock now computer edit engineering so this is the technology which is concerned with the computers to analyze the quad model and allowing the designer to simulate the study how the product will behave so that to validate the design what are the different softwares that can be used in the computer edit engineering or engineering analysis like there is a nc software hyper works ls dana nastron n also the solid works so these are the some of the applications regarding we can call this computer edit engineering so there is one question that is in front of you what are the components of automation just think about this question so the components of automation like may be the flexible manufacturing system or with the computer integrated manufacturing cnc machine tools automatic storage and retrieval system automatic guided vehicle these are some of the components of automation these are the references thank you thank you very much
