Machine tool and control method

摘要

The method involves controlling a current from power source. The controlled current is fed into magnetic coils (46,47) at target value during an acceleration phase. The acceleration phase is terminated when change of current flowing in magnetic coil or change of control variable of a control circuit of the power source is consistent with stored pattern for the change at an impact of striker (4) on anvil. An independent claim is included for a machine tool.
