AN INDUTRY PERSPECTIVE ON THE BEGININGS OF CAD/ CAM

ABSTRACT: This paper is a discussion of the early days of CAM-CAD at The Boeing Company, covering the period approximately 1956 to 1965. This period saw probably the first successful industrial application of ideas that were gaining ground during the very early days of the computing era. Although the primary goal of the CAD activity was to find better ways of building the 727 airplane, this activity led quickly to the more general area of computer graphics, leading eventually to today’s picture-dominated use of computers. The paper started as an internal exchange of memories between some of the people primarily concerned, but is now offered as the possible start of a discussion involving other such initiatives during that period.
1. INTRODUCTION
Several independent early steps had taken place towards the idea of computer-aided design (CAD) during the early 1960s. CAD is the use of computer technology to aid in the design of a product [3]. That is, it is the mathematical definition of lines and surfaces for drawing lines and cutting parts with the computer. Computer-aided manufacturing (CAM) comprises the use of computer-controlled manufacturing machinery to assist engineers and machinists in manufacturing or prototyping product components, either with or without the assistance of CAD. CAM certainly preceded CAD and played a pivotal role in bringing CAD to fruition by acting as a drafting machine in the very early stages. All early CAM parts were made from the engineering drawing. The origins of CAM were so widespread that it is difficult to know whether any one group was aware of another. However, the NC machinery

    With the purchase of CAD/CAM the sales would begin to increase in result to Polymold having the technology to make the product more efficiently and effectively. The fixed costs of Polymold will increase by a large amount due to the new computer cost. This is a negative effect on the company but it should not be taken as too big of a threat. The biggest threat is the competitors in the industry beginning to increase their own structures and strategies in making the product at the most efficient way possible and the consumers would like to receive the best product possible. Without the CAD/CAM it leaves workers to sketch the plastic…

    In order to use CAD effectively as a design tool, the designer must have the skills necessary to create, edit, and manipulate a 3D model of a part in order to create a realistic representation of an imagined object. In this activity you will build on the CAD skills that you learned in Activity 5.2b Introduction to CAD Skills. You will learn about and use additional tools and features available in most CAD programs and apply your new CAD skills to the creation of more complex parts that will be used in later activities (as components in the assembly of parts) to create complete products (including a complete Automoblox vehicle and a Button Maker machine).…

    A CAD model can quickly display an engineer’s ideas in a realistic way. And those models can be used to generate technical drawings that can communicate the information necessary to make the idea a reality. In order to generate a 3D model, designs must start with sketches that are generated within the CAD program. These computer generated sketches will appear resemble hand drawn sketches in geometry (the combination of points, lines, and shapes), but have big advantages over hand drawn sketches. One important difference between a freehand sketch and a CAD sketch is accuracy. The lines of a CAD sketch can be drawn perfectly straight, with start and end points that occur in exact locations in space. By using numeric (dimensional) constraints a line may also be given precise length, placed a specific distance from another sketch feature, or constrained to be oriented at a specific angle from another straight line. By applying geometric constraints a line can be made perfectly horizontal or vertical. If more than one line is being sketched, they can be made perfectly parallel or perpendicular, collinear, or equal in length. Lines can be constrained to be tangent to circles or arcs, and two circles can be constrained to be concentric. In order to precisely model a part, the designer must be able to use dimensional and geometric constraints within the CAD program.…

    As the population grew rapidly the demands for faster and more accurate plans did also. Once again drafters looked for a new way to draw. They decided to turn to the computer. In the 1950s MIT discovered the capability to display a computer-generated image on the screen (Zandi, 5). Up until the mid to late 1970s drafters used this technology just for mathematical calculations (Goetsch, 23). Then they discovered that the computer could be used to display more than just numbers. They found that they could use it to draw on. It wasn't until the early 1980s that this new technology caught on (Goetsch, 23). Drafters found that using computers was much quicker, more accurate, and much neater than hand drawn plans. They had found their solution, Computer Aided Drafting and Design or CADD.…

    The connection between CAD and CAM is that you can import a CAD drawing straight the software to CAM. With computer-aided design (CAD), engineers can use computers o change design quickly and store drawing by machine. Then they do much of this process over the Internet: do remote conferences while screening and developing plans and drawings mutually. The electronic drawings are then accessible to make rapid prototype. When the prototypes are acceptable, the electronic drawing and material specifications can be transferred from CAD systems to Computer-aided manufacturing (CAM) systems. This systems process the data to train machines, as well as robots, how to produce the parts and collect the product.…

    The goal of this project was to help students become familiar with a program created by the company Siemens called NX, specifically versions 8.0 and 8.5. Somewhat similar to the program SolidWORKS, NX allows the user to create sketches of simple and complex objects, and then create a 3-D model of the object. Also, an assembly of these models can be made by assigning constraints to create an overall 3-D assembly model. This project was made to utilize NX in order to create an assembly model of a skateboard, made of 6 different parts: The Bearing, The Board, The Bushing, The Connection, The Shaft, and The Wheel. Some parts were easier than others, such as the Shaft, which just required a sketch of a circle to be extruded to a certain length. Others required much more commands, such as the Connection and the Bearing, which required a sweep and many other constraints. Before the project was assigned, students were given many homework assignments that required them to create a part using NX, which didn’t require many commands. Over time, these assignments became more and more challenging, requiring more and more commands. After these parts were modeled, students were taught how to create an assembly using the parts modeled, which use constraints to keep them together such as Concentric, Touch Align, and Center. In order to model the 6 parts of the Skateboard Assembly, students were given IGS files as a reference. These files allowed students to open them in NX and use the Drafting environment to infer dimensions to recreate the part on their own. Dimensions in the sketches were the most important, especially when putting the board together, as dimensions that were not proportional to one another could cause an error in the assembly environment when assigning constraints.…

    In the world of construction, material, labor, equipment, time and money are some of the most important factors. A speedy well planned site could decrease the construction cost drastically. Up until 1971, there was no way to use a computer and all site drawings had to be done in hand. This was very time consuming and would usually delay the rest of the construction process. During that year, a program was developed, CORELAP was one of the first site layout applications for the computer but still had its faults. Other tools for the computer were designed but most had major faults and none gained wide acceptance by the civil engineering industry. But by 1987, AutoCAD was developed and sold to computers everywhere. (Sadeghpour, Moseli & Alkass, 2006)…
