Method and system for parameter extraction of a cutting tool

A method for extracting parameters of a cutting tool, the method comprising:

• positioning the cutting tool on a moveable stage;
• performing one or more rotary scans of a first section of the cutting tool to generate a scanning point cloud;
• indexing a plurality of points of the scanning point cloud;
• detecting one or more feature points based on the indexed scanning point cloud;
• and
• extracting one or more parameters based on the detected feature points, wherein the cutting edge points comprise one or more of initial cutting edge points, refined cutting edge points, and theoretical cutting edge points, and wherein detecting the cutting edge points comprises detecting a first initial cutting edge point having a furthest distance from a central point of the scanning point cloud, and detecting at least one of other initial cutting edge points based on the index of the points and a flute number of the scanning point cloud.

A system for extracting parameters of a cutting tool, the system comprising:

• a stage configured to position the cutting tool;
• a range sensor configured to scan the cutting tool;
• and
• a controller configured to:
• control the range sensor to perform one or more rotary scans of a first section of the cutting tool to generate a scanning point cloud,
• index a plurality of points of the scanning point cloud,
• detect one or more feature points based on the indexed scanning point cloud, and
• extract one or more parameters based on the detected feature points, wherein the controller performs a first rotary scan of the first section to generate a first scanning point cloud, and segments the first scanning point cloud, and further performs a second rotary scan of the first section based on the segmentation of the first scanning point cloud to generate a second scanning point cloud, and wherein the scanning point cloud comprises the second scanning point cloud.
