2. Milling
Reduce vibration
Workpiece set up and machine stability are two important things to
consider carefully to minimize vibration.
Workpiece
– Affix the workpiece in the most favourable way to support the
cutting forces which arise during the machining process
– Use milling concepts with design and entering angle that gener-
ate cutting forces in the most stable direction of the workpiece
– Optimize the machining strategy and direction to obtain the most
stable cutting condition as possible
Machine
– Machine condition have a large influence on vibration. Excessive
wear of the spindle bearing or feed mechanism will result in poor
machining properties.
