A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A camera assembly is used to monitor articles for washing within the wash basket. Specifically, a controller of the washing machine appliance uses the camera assembly to obtain a reference image and one or more test images, which utilize image recognition to assess turn-over of the articles for washing during a given wash cycle. When turn-over performance is inadequate, a controller may adjust one or more operating parameters of the wash cycle to improve performance. Turn-over performance of the wash cycle is determined to be adequate once the image recognition process fails to find adequate correlation between the reference image and the test image a predetermined number of times.

A method for controlling air volume including: 1) inputting a target air volume into a microprocessor control unit of a motor controller; 2) starting a motor by the motor controller and allowing the motor to work in a steady state under a rotational speed; 3) recording the torque and rotational speed in the steady state, establishing a functional relation formula Q=F (T, n, V) for calculating the air volume, and calculating an air volume in the steady state; 4) comparing the target air volume with the calculated air volume; 5) re-recording a steady torque after the motor falls on a new steady state under an increased or reduced rotational speed, and recalculating the air volume in the new steady state; and 6) repeating steps 4) and 5) to adjust the rotational speed until the calculated air volume is equal or equivalent to the target air volume.

An automated computer-implemented method for generating commands for controlling a computer numerically controlled machine to fabricate an object from a workpiece, the method including the steps of selecting a maximum permitted engagement angle between a rotating cutting tool and the workpiece, selecting a minimum permitted engagement angle between the rotating cutting tool and the workpiece, and configuring a tool path for the tool relative to the workpiece in which the engagement angle gradually varies between the maximum permitted engagement angle and the minimum permitted engagement angle.

A motor control system includes first processing circuitry that controls a motor. An upper-level communication path connects an upper-level communication port of the first processing circuitry to second processing circuitry that sends an instruction to the first processing circuitry via the upper-level communication path. A lower-level communication path connects a lower-level communication port of the first processing circuitry to a plurality of devices connected in series to each other. The devices include rotational angle detection circuitry and output circuitry. The rotational angle detection circuitry detects a rotation angle of the motor.
