Latest Patents

One of his latest patents is focused on adaptive control for machine tools. This invention allows a turning machine to adjust its machining rate to maintain a constant horsepower at the cutter tip, regardless of variations in workpiece and cutter parameters. The system intelligently controls the machine drive and tool feed to achieve the required surface feet per minute (SFM) and inches per revolution (IPR) values, while adhering to maximum and minimum limits. The adaptive control features 'Speed' and 'Axis' override controls, enhancing its versatility. The adjustment rate of SFM and IPR is inversely proportional to the measured system gain, optimizing the control loop's response factor. Additionally, the cutter tip horsepower is calculated by accounting for electrical losses, mechanical friction, and the power needed for acceleration. The system also monitors cutting efficiency to manage tool wear, breakage, and protection functions, incorporating soft engagement and disengagement features for a seamless adaptive machining process.
