AX high-performance milling cutters

Optimization of the cutting data and machining strategy Height H max Displacement A max Surface Ra max Root radius Non-supported wall Min. radius R min Width W min Length L max Component properties The tool, cutting data, and machining strategy are selected on the basis of the component. The following notes on the individual component properties and their effect on the machining process can be used to optimize the manufacturing time and improve the manufacturing quality. Min. radius R min determines the maximum cutter diam- eter. Rule: R min x0.90 ≥ r tool. In the case of critical radii or high cutting edge utilization, a 60% reduction of the feed rate should be programmed. For the non-supported wall , synchronization should be achieved by milling the front side first, as long as the web is still sturdy. To prevent the webs from buckling, we rec- ommend you traverse straight over the edge of each web. The height H max , width W min and length L max together determine how weak the component is at any given point. For extremely thin walls, the speed and feed rate of the PF and F cutting data recommendations should be reduced by a further 30%. The displacement A max is influenced by the machining strategy. In the case of very thin wall thicknesses, the prefinish and finish passes must be carried out. Reduced ae and fz values improve the displacement. The inner and outer sides of the wall should always be machined one after the other with the same appli- cation in order to achieve the best homogenization result and uniform qualities. The parameters specified produce a high surface quality R a . The milling dynamics are the most important control parameter when it comes to avoiding vibration. The speed should be reduced to achieve excellent finishing results. In addition, the milling cutter needs time to build up a suitable cutting pressure and provide optimum chip formation. [ 7 ]
