Methods of inducing segmented flow in a material in which a ductile flow mode would otherwise occur during machining. A monolayer molecular film is formed on a surface of a body of a material in a state such that the material exhibits ductile flow when subjected to shear. The monolayer molecular film has molecules each having a head group adsorbed to the surface, a terminal group, and a hydrocarbon chain therebetween having a chain length of greater than 6. A surface portion of the body is removed by engaging the body with a tool in a contact region below the surface of the body and moving the tool relative to the body to remove the surface portion and the monolayer molecular film thereon. The monolayer molecular film induces segmented flow in the material during the removing of the surface portion.

A laser assisted micromachining system, includes a working sliding, a tool module, a laser module, and a temperature control module for the processing of a workpiece. The laser module is disposed in the working slide and moves with the working slide in three-dimensional space. The temperature control module includes a temperature sensor, a cooler, a controller and a coolant, which detects the real-time temperature value of the cooler. The cooler is located in the working slide and supports the tool module. The controller controls the working state of the cooler according to the temperature feedback. Control signal induced by the temperature indicator, and the working state of the cooler are controlled by the controller. The coolant is used to control the temperature distribution of the cooler in the setting range. At the same time, the invention also provides a temperature control method for the laser assisted micro machining system.
