  • Patent number: 10061294
    Abstract: A numerical controller sets a parameter actually used for servo control on the basis of command data generated by analyzing a machining program. Based on the set parameter and a predefined allowable position deviation amount, a feed speed which is given by a position deviation not exceeding the predefined allowable position deviation amount is calculated. Then, when a feed speed commanded by the command data is larger than the calculated feed speed, the feed speed commanded by the command data is clamped at the calculated feed speed.

  • Patent number: 10048677
    Abstract: A numerical controller decodes a block read out from a machining program, calculates execution data to be used for control over a machine tool, and determines whether a travel amount resulting from travel instructions for control axes of the machine tool is existent or not based on the calculated execution data. If the travel amount resulting from the travel instructions for the control axes is not existent as a result of such determination, processes for the present block are omitted and cycle time is thereby shortened.

  • Patent number: 9957074
    Abstract: A method of controlling an upstream and a downstream process wherein the upstream process conditions a stream of product delivered to the downstream process is provided. The control method uses an empirically determined formula to determine a metric for adjusting the activity of the upstream process to thereby adjust the rate with which the upstream process conditions and feeds a stream of conditioned product to the downstream process. The empirically determined formula determines the metric using two input variables: a duty cycle setting of the upstream process and an output rate of the downstream process expressed as a decimal amount of the output rate set-point.

  • Patent number: 9921572
    Abstract: Finite element methods for compensating for springback in aircraft parts meet the visual appearance and aerodynamics of complex parts including those made of fabricated sheet metal. The methods can be used to make narrow parts (e.g., leading edge and slats) and double negative curvature parts, and do not need to leave marks on the surface of the sheet so that visual aspects are not adversely affected. The point to point compensation technique uses approach equations with constants adjustable for curves. The constant(s) used depend on geometry and type of forming (e.g., stretch or hydraulic press). Use of mechanical properties of the material is not required.

  • Patent number: 9914278
    Abstract: Methods, computer-readable media, and systems described herein relate to producing on-demand packaging. For example, packaging can be automatically produced on-demand and be sized and configured for use with a customized set of items. In one aspect, a request for multiple items is received and a packaging customization engine accesses an information store that includes information about each of the requested items. The information may include dimensional information about the three-dimensional size of the items. The packaging customization engine may use the dimensional information to simulate a model arrangement of all of the requested items, and then calculate the dimensions of a box or other package that can provide a precise fit for the items when physically arranged consistent with the model arrangement.
