Patent number: 10377124Abstract: An additive manufacturing method for delivering a flowable material from a nozzle of a programmable computer numeric control (CNC) machine, the nozzle being configured to translate along a first axis, a second axis perpendicular to the first axis, and a third axis orthogonal to the first and second axes. In one embodiment, the method includes actuating an extruder to form a flowable material, delivering the flowable material to a pump, sensing a pressure of the flowable material, and adjusting at least one of a speed of the extruder and a speed of the pump based on at least one of the sensed pressure and a rate of translation of the nozzle along one or more of the first, second, and third axes.Type: GrantFiled: August 31, 2016Date of Patent: August 13, 2019Assignee: Thermwood CorporationInventors: Kenneth J.

Publication number: 20040027038Abstract: The present invention is an apparatus and a method of processing a workpiece on a worktable. Once the workpiece is properly loaded on the worktable, a moveable workpiece locator can either manually or automatically direct the workpiece to a predetermine location on the worktable so that a demarcation can be impressed by a marking disk on a predetermined location on the workpiece and the workpiece can be automatically cut to a predetermined length.Type: ApplicationFiled: August 12, 2002Publication date: February 12, 2004Applicant: THERMWOOD CORPORATIONInventors: Robert Gaesser, Kenneth J.
