The invention provides a method, device and equipment for fitting a hob abrasion profile and a storage medium, and relates to the field of tunnel engineering. The method for fitting the wear contour of the hob comprises the following steps of dividing the outer contour of the hob into a plurality of contour sections by utilizing a plurality of measuring points on the outer contour of the hob, andcalibrating one contour section for every two adjacent measuring points; for each contour segment, obtaining an interpolation polynomial of the contour segment by using the position data of the measurement point of the contour segment, obtaining the value of the position data corresponding to any data point on the contour curve of the contour segment represented by the interpolation polynomial, and enabling the value of the position data of the measurement point to be within the interval calibrated by the maximum value and the minimum value in the values of the position data of the measurementpoint; utilizing an interpolation polynomial of the contour section to fit and obtain a contour curve of the contour section; and obtaining an outer contour curve of the hob based on the contour curves of all the contour sections. By means of the technical scheme, the function of obtaining the abrasion contour (namely the outer contour) of the hob through fitting can be achieved.
