摘要： The present invention relates to a workholding device and method, and specifically provides a workholding device for positioning a workpiece on a machining equipment, which comprises: a sacrificial tray for supporting the workpiece; a workholding layer formed of a curable material applied on the sacrificial tray, which secures the workpiece at a predetermined position on the sacrificial tray upon completion of the curing, wherein the sacrificial tray and the workholding layer are allowed to be damaged by a cutting head of the machining equipment during machining of the workpiece; a curable material collector arranged below the sacrificial tray to collect the curable material that detaches from the sacrificial tray during the application of the curable material, the curing of the curable material, and/or the machining of the workpiece; a curing processing unit comprising a controller and a curing rate regulator, wherein the controller controls the curing rate regulator to regulate curing rate of the curable material by changing at least one factor that affects curing; and a platform assembly for supporting the sacrificial tray, the curable material collector and the curing processing unit, which is configured to be removably installed on the machining equipment.

摘要： A system and a method allow for the removal of excess material from a dental appliance. The system includes at least one 5-axis computer numerical control (CNC) machine and at least one administrative computing system. The administrative computing system is used to determine the trim line for the dental appliance. The administrative computing system is also used to determine a tool path for an automated tool that is an integrated part of the 5-axis CNC machine. The tool path is then relayed from the administrative computing system to the 5-axis CNC machine. The 5-axis CNC machine is used to machine off the excess material from the dental appliance along the trim line, while the automated tool follows the tool path.

摘要： The invention relates to a dental milling machine which has a closed milling chamber (12). Said milling chamber has an air inlet opening and an outlet which are substantially opposite each other relative to the milling chamber and generate an air stream. Said air stream sweeps over a machining area in which a milling tool subjects the workpiece to a milling machining step. One end of the milling chamber (12), in particular the front end, has a door that can be opened. The base (42) of the milling space (12) runs at least partially at an angle and in particular is rounded off and the outlet (40) is connected to the lowest region of the base (42).

摘要： Technology for milling selected portions of a workpiece by a cutting tool of a numerical control machine is described. The described technology provides methods and apparatuses for milling areas of a part so that more aggressive machining parameters can be used in the toolpath, thereby resulting in reduced machining time and load. The described technology additionally determines directions of the tool axis vector at points along a toolpath in order to achieve a desired part shape while optionally maintaining high material removal rates.
