Embodiment Construction
[0032] The present invention will be further described below in conjunction with the drawings and embodiments.
[0033] Such as figure 1 As shown, an online prediction method for future tool wear provided by the present invention includes the following steps:
[0034] Step 1: Take the tool wear from the 1st moment to the mth moment in the machining process as the input sample to form a two-dimensional tensor M with a structure of [m,1] 1 , Take the tool wear at the time m+1 to m+n as the output sample to form a two-dimensional tensor N with the structure [n,1] 1 , Two-dimensional tensor M 1 And the two-dimensional tensor N 1 A sample pair is formed, where m is the number of historical moments of the user-defined tool wear, and n is the number of future moments of the user-defined tool wear; then the tool wear from the second time to the m+1 time As an input sample, form a two-dimensional tensor M with the structure [m,1] 2 , Take the tool wear from m+2 to m+n+1 as the output sample...
