A MODEL FOR MICRO THREAD MILLING OPERATION (MTMO)

Résumé

The machining of miniaturized components is now a days one of the most important fields of interest in manufacturing and a new tool similar to thread milling is appearing in the market to produce micro threads. This paper investigates a thread making process in micro scale, called micro thread milling operation (MTMO) and presents a new model. The model assumes that the feed direction is linear neglecting the axial feed, which is reasonable for low rates. A chip thickness and mechanistic cutting force model is developed for a thread milling operation with a micro milling tool. As the depth-of-cut to tool diameter ratio is much higher in micro thread milling than the conventional one, the chip thickness is calculated considering the trajectory of the tool tip while the tool rotates and moves continually. Micro milling specific cutting pressure is used as calibration. Numerical results for two different commercial tool dimensions are presented and tool run-out is included.
