TOOL HOLDER ASSEMBLY AND METHOD FOR MODULATION-ASSISTED MACHINING

摘要

A tool holder assembly (10) and method for intentionally inducing modulation in a machining process. The tool holder assembly is configured for mounting in a tool block (22) on a machining apparatus and includes a tool holder body (20) configured to be secured to the tool block of the machining apparatus, a tool holder (14) mounted on the tool holder body and configured for securing a cutting tool (12) thereto, an a device (24) for imposing a superimposed modulation on the tool holder so as to move the cutting tool relative to the tool holder body and thereby relative to the tool. The tool holder assembly is useful in a process for producing chips having a desired shape and size, and particularly to a method of controllably producing nanocrystalline chips.
