Patent number: 10061294Abstract: 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.Type: GrantFiled: February 9, 2016Date of Patent: August 28, 2018Assignee: FANUC CorporationInventor: Takenori Ono

Patent number: 9921572Abstract: 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.
