Title:
制御された材料の除去を実現するための研磨工程のモデル化
Document Type and Number:
Japanese Patent JP2006513869
Kind Code:
A
Abstract:
In general, techniques are described that allow an abrasive manufacturing process to achieve a controlled performance parameter, e.g., an amount of material removal, without requiring the use of feedback controls within the abrasive manufacturing process. For example, a system includes a machine to abrade a workpiece with an abrasive article, and a controller to control the application of the abrasive article to the workpiece by the machine to achieve a substantially constant cut rate for the abrasive article. The controller controls one or more process variables in accordance with an open-loop mathematical model that relates the cut rate of the abrasive article to an application force of the abrasive article to achieve controlled material removal. For example, a constant rate of cut can be achieved or a fixed amount of material can be removed while abrading one or more workpiece in accordance with the model.
