HSM is not simply high cutting speed. It should be regarded as a process where the operations are performed by very specific methods and on high precision production equipment.
HSM is not necessarily high spindle speed machining. Many HSM applications are performed at moderate spindle speeds and with large sized cutters.
HSM is performed in finishing on hardened steel at high speeds and feeds, often 4-6 times conventional cutting data.
HSM is High Productive Machining of small-sized components in roughing to finishing and in finishing and super-finishing in components of all sizes.
HSM will grow in importance the more net shape the component become.
HSM today, is mainly performed on taper 40 machines.
