16 Conventional Milling is Preferred Over Climb Milling There are a variety of arguments for this but the primary issue is one of which way the tool deflects Since micromills are particularly susceptible to deflection a conventional milling approach is preferred since deflection will be along the tool path and not into the workpiece

The shortest tool setting is recommended to reduce the tool deflection and chatter in NC machining An accurate cutting force model of ballend milling is essential for precision prediction and compensation of tool deflection that dominantly determines the

During the machining processes particularly the intermittent cutting like milling when excited by the external force or impact the cutting process becomes unstable and flexural deflection may occurs in the static situation or large vibration may happen in the dynamic process which will deteriorate the
