A processing system includes a cutting tool for milling, a plurality of sensors, and a processing unit. The plurality of sensors each is configured to measure a physical quantity that indicates a state related to loads on the cutting tool during cutting. The processing unit is configured to generate, based on measurement results from the respective sensors at a plurality of measurement time points, measurement data that is related to the loads in two directions on a plane perpendicular to a rotation axis of the cutting tool and that includes two-dimensional data at each of the measurement time points, and to perform a determination process concerning cutting in which the cutting tool is used, based on a two-dimensional shape indicated by the generated measurement data.

An analysis device according to the present disclosure analyzes the state of a machining tool. The analysis device includes: an acquisition unit that acquires a measurement result from at least one sensor fitted to the machining tool; a computation unit that performs data processing to the measurement result acquired by the acquisition unit; and an image processing unit that displays a first image and a second image on a display screen, the first image displaying the measurement result acquired by the acquisition unit in time-series, the second image displaying a computation result after the data processing is performed by the computation unit. The image processing unit displays, as the second image, the computation result corresponding to the measurement result for a specific time period in the first image.
