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.
