Abstract: Cold forming tool including at least one penetration zone having teeth and a calibration zone having teeth. The teeth having a tooth height that increases substantially from the at least one penetration zone to the calibration zone. A distance between an outer surface and a forming reference axis decreasing from the at least one penetration zone to the calibration zone. A rate of increase in the tooth height between the at least one penetration zone and the calibration zone being greater than a rate of decrease in the distance between the outer surface and the forming reference axis between the at least one penetration zone and the calibration zone. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: The invention relates to equipment for cold forming blanks of metallic parts by revolution, particularly for forming grooves or a knurling. The tool has regularly-spaced teeth (D) on a tooth gullet (F), with a penetration zone (A) followed by a calibration zone (B). According to the invention, the teeth have a height (h) that increases substantially from the penetration zone to the calibration zone, whereas the tooth gullet is at a decreasing distance from the forming reference axis (X) of the tool.

Abstract: A system and method automatically configures protocol layer parameters in terminal and carrier equipment. The system includes a terminal equipment having an automatic configuration program. The automatic configuration program controls the operation of the terminal equipment and sends a series of probe to the carrier equipment. Each probe is constructed to test a specific parameter value, and to restrict a set of potential values for the parameter. The automatic configuration program receives answers back from the carrier equipment, which may accept or reject, or not respond to the probe. Based on the the probe, any previous probes, the answer, any previous answers, and the set of values for the parameter, the automatic configuration program constructs another probe in accordance with another value of the parameter. This other value is determined by restricting the set of potential values that may be used to configure the parameter.
