While the maximum chip rate in slotting and contouring are the criteria usually considered, the performance of the plunge milling tool is often ignored. Polytool elements software#The images obtained from the software simulation also support the technical documentation, making it easier to promote this solution to DIXI Polytool's customers.ĭetermining the optimum geometry is also a key parameter for obtaining a high-performance milling tool. Ansys Discovery was able to show that the ring system not only accelerated the fluid under certain conditions, but also allowed a much higher cutting speed than without the ring. The advantages of adding the ring to the outlet of the spray channels were demonstrated. By using Ansys Discovery, DIXI Polytool's R&D team was able to compare different solutions quickly and cost-effectively. Using high-speed lubrication makes these simulations complex and unrealistic. This software is very expensive and does not always give the expected results. Software is available to simulate chip formation and stress distribution on the tool. Chip formation and chip evacuation are complex phenomena to understand, especially when lubrication is used. While it is relatively easy to measure the performance of one tool compared to another, it is much more difficult to understand the reasons why and find ways to improve it. Simulation has helped DIXI Polytool to develop new tools This is made easy by the use of a coolant hole towards the flute, through which high speed lubricant flows. The solution adopted by DIXI Polytool is the integration of the patented "Cool+" coolant system at the interface between the chip and flute face. Controlling this process is both a technical and commercial challenge, allowing us to stand out from the competition. This way, the lubricant will effectively dissipate the thermal energy generated, reduce the frictional forces on the cutting face and ultimately reduce cutting times. For best results, the lubricant jet must be directed precisely at the interface between the chip and the cutting surface and must also have optimum pressure and velocity. One of the major roles of the lubricant is to reduce the friction of the chip on the cutting face, but also to dissipate the heat generated by chip formation. Without lubrication, the heat generated by the machining process quickly becomes too great and leads to the deterioration of the cutting edge, or even its destruction. Increase productivity by improving lubricationĭuring processing, the material is sheared off and then slides towards the cutting surface, generating a high level of friction on it. ![]()
