A workpiece shifting prevention device includes a platform, which is configured for supporting a workpiece thereon; a sensor group mounted in the platform, which is configured for measuring pressures at different points on the platform and converting the pressures into voltage signals; an amplifier group connected to the sensor group, which is configured for amplifying the voltage signals output from the sensor group; and a single chip connected to the amplifier group, which is configured for receiving and processing the amplified voltage signals. The single chip checks if the voltage signals output from the sensor group are equal, and if not, adjusting machining parameters of an implement connected thereto.
