Abstract
A forming method includes using at least one forming tool to form a material of a workpiece and using a lubricant between the, material and the at least one forming tool. The lubricant has a viscosity that is modifiable by applying or varying a field.
Claims14
A forming apparatus for forming a material of a workpiece with at least one forming tool using a lubricant, comprising:
- a field generator configured to generate a field influencing the viscosity of at least one of an electro-rheological and magneto-rheological lubricant and further configured to modify the viscosity of the lubricant between the material and the at least one forming tool by varying the field during the forming of the material while the at least one forming tool is influencing the shape of the material.
The forming apparatus according to 1, wherein the at least one forming tool includes at least one electrode part to generate an electric field.
