Abstract
A tool-holder for a milling machine is composed of a first rotating portion with a coupler attachable to a spindle drive shaft of the machine, a second rotating portion turning as one with the first portion and equipped with a chuck to hold a tool, and a mechanism designed to detect undulations on a surface being milled. The second rotating portion is capable of axial movement relative to the first rotating portion, so that when the tool-holder is traversed along a prescribed trajectory referable to a nominal surface, the undulations on the actual surface of the panel and the extent of their deviation from the nominal surface can be sensed and quantified through the agency of detection mechanism, and a corresponding axial movement induced in the second portion of the tool-holder to compensate the variation and maintain a constant milling depth, thereby improving the quality of finish-milling operations on technological materials such as panels of carbon fiber composite.
