Abstract

Since computerised numerical controlled (CNC) machines began to be used in the manufacturing industry, accurate determination of tool path strategies has always been an important problem area. In addition to the increasing design expectations e specially in products and parts, developments in CNC machines have increased the efficiency expectation in tool path applications. The tool path can also vary according to the nature of the work and the geometric structure needed. Different tool path strategies can be used depending on product structure and machine characteristics in different sectors. The geometry of the workpiece to be machined, especially designed for machining complex shaped parts, plays an important role in determining the cutting tool path and tool to be used. In addition, the preferred tool path strategy raises issues such as reducing manufacturing costs, reducing manufacturing time and improving surface quality. In this context, the parameters such as the form of the workpiece, the quality of the workpiece, the characteristics of the cutting tool, the machine characteristics, the cutting conditions are among the main factors to be considered in the tool path evaluations.
In this study, tool path strategies for a sample piece of product were evaluated in a CNC woodworking machine. A three-axis CNC machine was chosen for the application. For this purpose, first of all, product part is modeled in CAM program and tool path strategies are developed on product design. These strategies were applied on CNC woodworking machine and the results of preferred tool path strategies were evaluated with comparative analysis. As a result of the research, the approaches that can be applied in determining the correct way of team strategies and the benefits that can be obtained are discussed.
