A diagnostic method of diagnosing a press for the presence of any abnormality that deteriorates a quality of a product manufactured by the press, wherein physical value (Fs, Fsi, Ff, Ffi, Fp, Fpi, Xsi, Xei, Xy, Xz, Vx, Gx, Gy, Gz, Temp A, Temp B, Va0, Vf0, Vd0, V, Aa, Ag, Az, Afi, Ps, Pmai, Psa, Paa
A diagnostic method of diagnosing a press for the presence of any abnormality that deteriorates a quality of a product manufactured by the press, wherein physical value (Fs, Fsi, Ff, Ffi, Fp, Fpi, Xsi, Xei, Xy, Xz, Vx, Gx, Gy, Gz, Temp A, Temp B, Va0, Vf0, Vd0, V, Aa, Ag, Az, Afi, Ps, Pmai, Psa, Paa, Pyai, Peai, Pzai) such as a load generated at a selected portion of the press during operation of the press is detected, and the press is diagnosed for any abnormality, on the basis of the detected physical value, and according to a predetermined reference. For example, the diagnosis is effected based on: a waveform of a load detected in relation to a physical value which changes during a pressing cycle; a distribution of local values of the load detected local portions of the press; a correlation between the load and the physical value; a patter of variation of the load as the number of pressing cycles; a displacement amount, velocity or acceleration, or a temperature of a selected component of the press; or a capacity of a fluid used for a cylinder which produces a load or force.

[ What is claimed is:] [1.] A diagnostic method of diagnosing a press for determining the presence of any abnormality that deteriorates quality of a product manufactured by a pressing operation performed on a blank while a main slide of the press is reciprocated, the method comprising the steps of:detecting a selected one of a plurality of characteristics of a load generated at a selected portion of the press prior to a production run of the press, while the main slide is moved without the blank;determining the selected characteristic of the load detected prior to the production run of the press; andcomparing the determined characteristic of the load with a predetermined reference that permits the product to have an intended quality, and thereby determining the presence or absence of an abnormality, based on a result of comparing the determined characteristic of the load with said predetermined reference.
