Abstract
Systems, and/or methods for movement control of material removal systems and/or assemblies are disclosed, such as saws, grinders, polishers, and/or more general material preparation and/or testing machines, for example. A material removal system may include a material removal 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 assembly (e.g., via the actuators) based on one or more power, thermal, position, and/or other parameters that indicate whether the material removal tool is in contact with a sample.
Claims20
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 adjust movement of the material removal machine via the drive assembly based on a parameter of the material removal machine, wherein the parameter comprises one or more of a power parameter, a position parameter, and a thermal parameter.
A material removal system, comprising:
- a material removal machine comprising a material removal tool;
- a drive assembly configured to move the material removal machine along or about an axis;
- a tool actuator configured to actuate the material removal tool using electric current;
- a tool actuator controller configured to control the tool actuator, the tool actuator comprising a sensor configured to measure the electric current;
- and
- control circuitry configured to move the material removal machine via the drive assembly in a first mode when the electric current, or a change in the electric current, is below a threshold, and in a second mode when the electric current, or a change in the electric current, is above the threshold.
A method of moving a material removal machine, the method comprising:
- moving the material removal machine via a drive assembly, the material removal machine comprising a material removal tool;
- and
- modifying movement of the material removal machine in response to a change in a parameter of the material removal machine, the parameter comprising one or more of a power parameter, a position parameter, and a thermal parameter.
