On the Model and State of Electric Conduction in Tool-Workpiece Contact Zone in Electric Hot Machining;

Study of Characteristics of Tool Wear and Adaptability of Tool in Electric Hot Machining;

Study on the Key Problems of the Electric Hot Machining;

There are some problems in electric-hot machining such as low productivity and the easy-burning of tools.

Using the temperature distribution math models of laser heating and metal cutting, the temperature distribution of laser heating assisted cutting has been calculated through finite element numeric analysis.

Laser heating assisted cutting is an effective of for cutting ceramics.

Accordingto two successful technology,cutting with laser heating is supplied an cutting character of materials is changed.

As a new non -conventional machining technology concerned by machining community in the world, laser-assisted machining(LAM)is a combination of optics, material science, heat transfer, physics, mechanics and mechanical machining.
