Abstract: A work piece holding apparatus uses a magnetorheological fluid for holding a work piece firmly for machining process and/or measurements. The apparatus includes a cell with a hollow space in it and magnetorheological fluid is put into the hollow space. A special fixture with a hollow space in it is used to hold a work piece by screws in the wall or walls. The fixture with a work piece in it is fastened inside the cell dipped in magnetorheological fluid to absorb the extra force beyond the holding power supplied by magnetorheological fluid alone. It then overcomes any climbing that may happen during any process. A magnetic field is supplied to the cell to make the magnetorheological fluid work. It is well known that if a magnetic field is applied to a magnetorheological fluid, the viscosity of the fluid will be increased tremendously and behaves almost like a solid.
