Manufacturing industries are striving to reduce product costs to be competitive in the face of global competition. In addition, there is a need to improve quality and performance levels on an ongoing basis. Another important requirement is timely delivery. Given the nature of global exports and long cutting chains across several international borders, the task of continuing to reduce delivery times is a daunting task. The computer has the ability to perform various functions along with the production software. Computer skills are thus exploited not only during production work but also by the entire product development. Computers are needed to integrate the entire production system and thus transform the computer-generated designs into products.
Computer Aided Design (CAD) is the use of computer programs to assist in the design, modification, analysis or optimization of a design. CAD software is used to enhance designer productivity, improve design quality, improve textual communication, and create a production database. CAD data are usually in the form of electronic files for printing, machinery, or other computer-aided design work used in many fields. Its use in designing electrical systems is known as Electronic Design Automation or EDA. With mechanical design, it is known as Mechanical Design Automation (MDA) or computer-assisted writing (CAD), which involves the process of building a technical drawing using computer software. CAD software for mechanical construction uses vector-based drawings to illustrate traditional writing materials, or it may also produce raster drawings depicting the appearance of architectural elements. However, it involves more than just suspension. As with the actual writing of technical and engineering drawings, the CAD issue should convey information, such as equipment, procedures, size, and tolerance, depending on the specific program meetings. Computer aided engineering can be used to design curves and figures in a 2D space; or curves, solid surface, and stiffness in a three-dimensional (3D) shape.
Geometric modeling involves the use of a CAD system to improve the mathematical meaning of object geometry. Generally, a geometric model is fitted in the program. These include creating new geometric models from the basic building blocks found in the system. Geometric modeling is a branch of applied mathematics and a computer geometry that learns the methods and algorithms of mathematical interpretation of the shape. The shape studied in Geometric modeling is usually two or three, although most of its tools and principles can be used in sets of limited size.
Today most geometric modeling is done on computers and computer-based applications. Two-dimensional models are essential for computer typing and digital drawing. The three- dimensional models are central to computer-aided design and manufacturing (CAD / CAM), and are widely used in many applied technologies such as field engineering and engineering, crafts, landscape design and medical imaging. Geometric models are often divided into process and process models, which define the complete structure by the opaque algorithm that produces its appearance. They are compared to digital photographs and other models that represent the shape as a clip of a good common local divorce; and fractal models that provide a repetitive description of the shape.
Solid Modeling
This process is used to create the solid parts of the shape you want by joining and cutting different solid rolls. The solid end model is similar to the actual product but is more visible and rotated like a real product. There are two main types; direct where the model can be edited by reversing or converting the model directly to 3D; second one is a parametric in which a model is built using parameters.
Surface Modeling
This process is used to create an environment that is desirable by cutting, sewing and joining various areas to create the final model of shape.
Assembly
This process is used to assemble models made of a stronger or more durable model to form the final assembly. This is used to see the actual balance of all models and to see the actual performance of the assembly.
Drafting Detailing
This process is used to create 2D drawings of elements or assemblies; frequency directly from the 3D modeling, although 2D CAD can create direct 2D drawings.
Reverse engineering
This process is used to convert the actual part into a 3D CAD Model. Different types of instruments such as laser scanner, white scanner, CMM are used to measure or determine it.
Return on investment is one of the most important things to consider when using CAD design automation. Lowering product costs is a common challenge for manufacturers. Design automation solutions help to overcome this challenge as they offer a high cost reduction by reducing manual effort and speeding up construction. Cost reductions are combined with higher production results in a much higher RoI.
Design automation should be seen as a new way of working, not as a single project with a beginning and an end. It helps designers to perform repetitive construction tasks. This leads to a process designed, reduced costs, and increased productivity. In short, automation design empowers engineers to order custom completion days for custom engineering minutes in just minutes.
Manufacturers continually strive to innovate and improve their products in order to meet the high expectations of user experience, quality, and cost reduction. With effective communication across all departments and companies, automation strategies can be integrated with other business plans. In addition, a successful system allows you to climb well without attached strings – which utilizes many aspects of your design and engineering while bringing great benefits to your organization.
Companies are striving for seamless integration between all of their systems. Maintaining consistency between the various details conducted by the various departments can be a daunting task. Fortunately, automated systems are able to interact with broader business systems. Design automation starts in the engineering department. However, all company operations that meet engineering can ultimately benefit from automated design.
The automotive industry uses various event simulations to investigate the skills of several production shops involved in building vehicles such as body shops, paint shops, trim , chassis, assembly stores, and engine machinery stores, machinery stores and stamp shops. The simulation of bodybuilding systems in conceptual time, designing and constructing product life cycle stages allows the automotive company to investigate the impact of the use of tools, delivery and delivery systems There are two distinct approaches to analyzing physical performance. The first is modeling a body shop at station level. The second option is to model the body shop in the line or at the details level below. The channel-level simulation model is used to analyze the solitude of the sub-field.
Channel cycle times and downtime are included in the simulation model and are measured for subassembly power. Subassembly transfer can be directly compared to the acquisition of a physical store. As a general rule, the passage of the subassembly should be greater than the complete overhaul of the body shop or the new construction of the basement will be required. If complex handicrafts occur in a channel, these tasks can be added to a channel- level model. Modeling of travel, van and set times can indicate whether each station can meet the required time cycle of the subway. During the analysis of subway stations, a line level model can be developed. The output limitations for each subassembly model are included in the line level model and the transmission systems are modeled in detail. Interactions between subassemblies and delivery systems can be used to identify sets of subassemblies or individual subassemblies to identify issues in the physical store. Carrier measurement can be achieved by increasing the connection between the bottom of the
bottle and reducing the bath between the non-bottle areas. This process continues in the design phase.
Production managers and engineers remain concerned about quality improvements, reducing both production costs and delivery time. Globalization requires the introduction of new products with improved features at competitive costs. Another challenge is the reduction in product life. This requires a lot of time pressure on the product development cycle. Also notable is the tendency to customize large quantities that require excessive flexibility in production. Large-scale production is another important development in recent years.
Today’s customer expectations include high quality and performance, high technical skills, and timely delivery. All of this will be provided at a reduced cost due to global competition facing the manufacturing industry.
