The problem is therefore to select the optional and most economical combinations of processes and parameters for cutting-off a given product. To assist in this problem, each cutting-off tool or machine manufacturer and supplier recommends cutting conditions for their products which are neither consistent nor have a scientific base. As with other machining technologies, the cutting-off process domain has an abundance of data, but veiy little documented knowledge. It was proposed to undertake an investigation into the possibility of using a knowledge-based system for the selection of cutting-off processes, cutting-tools and the associated parameters. This project uses a survey to investigate the U.K. industry practice in the selecting of cutting-off process and machines used in their business and the nature of their business. The survey method, design and survey questionnaires as well as the findings are also reported. From the survey finding and interviews with experts, a prototype system structure has been developed. This system is similar to an expert's thinking in solving a problem. The structure of the system and how it works is also revealed in this report. The steps in building an expert system are discussed in this report, it states what is knowledge acquisition and the problems and methods used in knowledge acquisition. After the system was built, it was subjected to a through test programme. The testing procedure and industry validation process are discussed in the report. The testing results are analysed to show that the use of using an expert system in the selection of cutting-off process is feasible.

These regulations 4 do not apply to abrasive cutting saws, as their cutting mechanism and 5 dominant kickback mode differ from those of woodcutting saws. This work 6 combines theoretical and experimental tools to investigate abrasive saw 7 kickback. A theoretical model based on frictional engagement during a 8 pinch-based kickback event is shown to predict resultant kickback energy in 9 good agreement with experimental measurements. These measurements 10 were obtained using a specialized machine that generates pinch-based 11 kickback events and measures resultant kickback energy. Upon validating 12 the model, two representative saws, a circular cutoff saw and a chainsaw, 13 were tested using the prototype machine to evaluate their comparative 14 kickback risk.

  • Tube and Pipe Cutting Techniques; Advantages and Limitations Abrasive to Shear, Each Method Has Its Place
    TPJ ‐ The Tube & Pipe Journal® Tube and pipe cutting techniques; advantages and limitations Abrasive to shear, each method has its place By Leonard Eaton, Contributing Writer January 24, 2002 Many factors are involved in choosing a particular method or technology for cutting tube or pipe. Many factors are involved in choosing a particular method or technology for cutting tube or pipe. The basic factors that affect the cut are the tube or pipe material, wall thickness, squareness of ends, end‐conditioning requirements, and secondary process requirements. Other factors that play a role include production volume, cutting efficiency, overhead costs, and special requirements of the tube or pipe material. Abrasive Cutting Abrasive sawing is a basic, manual method of cutting‐to‐length product to the customer's specification in any alloy. An abrasive saw operates with a circular abrasive blade or resin‐ composition wheel—either wet or dry—that grinds through the product. Cut size capabilities depend on the machine. Some abrasive cutting machines can handle a solid round up to 4 in. outside diameter (OD). This general‐purpose method is useful for hand‐loading applications and small product runs that do not require critical end conditions. While an abrasive saw is easy to use and requires little or no setup time, it cannot provide a square cut or tight tolerances. Because the process uses a cutting or burning action, it is not efficient for thick‐walled material. It also might leave a heat‐affected zone (HAZ) that can affect secondary processing. While abrasive sawing is inexpensive and quick, it produces significant kerf and a heavy burr that might have to be removed by deburring.
