Abstract: A numerical controller performs PID control to control the move speed of an axis for driving a spindle such that a load value of the spindle becomes constant. When the spindle load value exceeds a threshold value, a speed calculation unit of the numerical controller calculates an override for the feed rate of the axis instructed by command data such that the load value of the spindle becomes constant, and, at the start of the speed calculation process, assigns the override just before the start of the speed calculation process to an initial value of an integral term or an offset for PID control.

Abstract: Calibrating the operation of a cutter used in a portioning system to cut workpieces into portions, wherein the workpiece is carried along a driven conveyance device past a scanner and then to a cutting apparatus. The calibration method employs a correction algorithm to correct for variables or limitations in the condition of one or more components of the portioning system and/or variations or limitations in the operation or operational capabilities of the portioning system. The correction algorithm may also factor in the physical condition, configuration, or composition of the workpieces being portioned, as well as whether the workpieces move on the conveyance device prior to and/or during the portioning operation.

For this reason, the user can use the parameter as a reference for reviewing the parameter setting for the purpose of shortening the cycle time or the like.

Abstract: Systems and methods for measuring and controlling fluid flow include an orifice plate defining a variable opening. The orifice plate includes an outer assembly comprising a central opening and an inner assembly extending through the central opening. The flow device regulates high and very low volumes of fluid with precision, inexpensively, with superior acoustics, reduced energy, and simpler design. The high turndown device permits use at lower velocities, thereby reducing noise generation and eliminating need for sound-attenuating liners. The high rangeability device combines several part numbers into fewer parts, thereby streamlining product portfolios. In some cases, cost benefits associated with the flow device allow equipment to be scaled back 100:1 rather than 10:1, providing energy savings, fewer product variations, simple and more robust applications. The device meets new and old building fresh air, comfort and energy codes.
