To easily grip and fix a work piece having a complicate curved surface onto a table by providing a gripping means for gripping and fixing the work piece through a process of pressing it to a plurality of reference plates installed on the table.
A material 2 of a turbine blade is positioned on two sets of reference plates 5a to 5d installed on an x-y table of a machining machine by fixing bands 4 by using the reference surfaces and gripped and fixed by gripping and fixing mechanisms 3 to 6 so as not to be moved. The material 2 of the turbine blade is positioned and fixed onto the x-y table in relation to a final product shape. Accordingly, a finished product having the final project shape is manufactured by performing cutting work or grinding work by controlling a machining tool 8 in relation to the work piece 2 on the basis of an NC data.
