US 11,511,381 B2 · Movement control of material removal systems

Abstract

A material removal system may control movement of a material removal machine based on whether a material removal tool is in contact with a sample. A material removal system may include a material removal machine (e.g., saw, grinder, polisher, and/or more general material preparation and/or testing machine) that is configured to move at the urging of one or more actuators. The system may further include control circuitry configured to control movement (and/or speed, acceleration, etc.) of the material removal machine (e.g., via the actuators) based on one or more power, thermal, position, and/or other parameters that indicate whether the material removal tool of the material removal machine is in contact with a sample.

Dependent claims

A material removal system, comprising:

a material removal machine comprising a material removal tool;
a drive assembly configured to move the material removal tool towards or away from a sample;
and
control circuitry configured to:
determine a threshold based on a tool property of the material removal tool, a sample property of a sample to be worked upon by the material removal tool, or a prior movement mode of the material removal tool, and
move the material removal tool in a first mode when a parameter, or a change in the parameter, is below the threshold, and in a second mode when the parameter, or a change in the parameter, is above the threshold,
wherein the parameter comprises at least a position parameter, the position parameter comprising a first distance between the material removal tool and the sample, or a second distance between the material removal tool and a mechanism retaining the sample.
