How to reduce vibration in milling

Cutting data and tool path programming. Always position the cutter off-centre in relation to the milled surface; With KAPR 90° long edge cutters or end mills, use low radial immersion: max a e = 25% DC and high axial cut: max a p = 100% D e In face milling, use a small depth of cut, a p, and high feed, f z, with round inserts or high feed cutters with small entering angles
