In precision machining, the condition of cutting tools deteriorates the product quality, defect rate, and productivity. Most small- and medium-size enterprises set the cutting tool replacement cycle through experience; however, this significantly differs from the actual number of tool replacements. To solve this problem, in this study, based on tool replacement data, FOM-Tool Monitoring, a smart factory operation management system, was used to perform 4M multi-dimensional analysis to analyze Min-Max and deviation in the number of times of tool use. The tool load waveform trend was also analyzed to verify the suitability of replacement, optimal replacement cycle, and conduct verification.
