Abstract: A workholding device for positioning a workpiece on a machining equipment, comprising a sacrificial support for supporting the workpiece, a workpiece holding layer formed of a curable material applied onto the sacrificial support, a curable material collector, a curing processing unit which comprises a controller and a curing rate regulator, and a bearing assembly for supporting the sacrificial support, the curable material collector and the curing processing unit, wherein the curable material is a solid which is viscous before curing and elastic after curing and has a melting point above 1000° C.

Abstract: 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 ma
