General recommendations for insert milling%uf0fc Down-milling is to be preferred as the first choice - especially for shoulder milling due to the 90%u00b0 setting angle.%uf0fc The milling strategy should be chosen so that the cutting forces are directed towards the support points of the clamping device; up-milling can be advantageous in some cases (Figure 1).%uf0fc The strategy regarding the positioning of the milling cutter on the component is of the utmost importance; planning in this regard should be carried out in great detail.%uf0fc For components that are clamped on a clamping tower, 90%u00b0 milling cutters with a positive insert basic shape (HM390) are recommended. A wide cutter pitch can significantly improve machining, even with negative systems. In any case, the forces should be directed towards the machine bed (Figure 2). We advise against systems with an adjustment angle < 90%u00b0 due to the higher axial force influence component.%uf0fc The choice of milling pitch should also depend on the stability of the entire system (machine, workpiece clamping, workpiece material, etc.)%uf0fc For SK40 and smaller machines, cutters with a wider pitch are recommended due to the limited stability.GoodStrategyBad StrategyFigure 1%u049a= 90%u00b0Figure 2F
