A thread rolling machine forming a threaded member from a workpiece includes a die, a device for rotating the die, a device for generating a load applied to the die in a workpiece-feeding direction, a member that deforms under the applied load during a thread rolling operation, a strain gauge that generates a signal indicative of the deformation of the member under the applied load, and a computer that calculates the load applied during thread rolling operation based on the signal generated by the strain gauge. The computer can generate a feedback signal permitting control of the applied load generated by the thread rolling machine by controlling either the load generating device or the die-rotating device. An operating method for a thread rolling machine is also described.
