Abstract: | The prediction of chip breaking in machining is an important task of automated manufacturing. A chip breaking predictive model has been developed to predict the chip breaking behaviour in steel turning with grooved tools. The model is based on the chip breaking limits theory. A web-based chip breaking prediction system has been developed and presented in this paper with industrial application examples. With the system, the chip breaking range in steel turning with grooved tools can be predicted under different cutting conditions. The experimental data for turning different steel material over a wide range of feed rates, cutting speeds and tool geometry showed agreements with the model prediction. The user-friendly system is accessible through the Internet for the purposes of cutting condition design and tool selection. Also, the system can easily be extended to contain new cutting tools and new workpiece materials with a small number of cutting tests.Nomenclature f Feed rate (mm/rev) - d Depth of cut (mm) - V Cutting speed (m/min) - fcr The critical feed rate (mm/rev) - dcr The critical depth of cut (mm) - r Insert Nose radius (mm) - Wn Insert chip breaking groove width (mm) - Cutting edge angle (deg) - 0 Insert rake angle (deg) - 01 Insert land rake angle (deg) - b1 Insert/chip restricted contact length (mm) - s Insert inclination angle (deg) - h Insert backwall height (mm) - WP Work piece - DB database |
