Purpose: The main purpose of this paper is to analyse the grinding processes and develop a search system of database for cutting tools. Design/methodology/approach: A tool grinding software with open architecture was used to analyse the grinding processes of square end mills, tapered square end mills, ball nose end mills, tapered ball nose end mills, radius end mills, tapered radius end mills, straight flute reamers, helical flute reamers, flat drills, twist drills, and step drills. According to the characteristics of these tools, 20270 data were established in the relational database. The SQL syntax was then utilized for writing the search algorithm, and the C++ Builder was employed for designing human machine interfaces of the search system of the tool database. Findings: A half of time on the tool design and the change of production line for grinding other types of tools can be saved by means of the proposed system. More specifically, the efficiency in terms of the overall machining time was improved up to 10.58%, 9.36%, 4.64%, and 7.52% for grinding the radius end mill, tapered radius end mill, twist drill, and step drill, respectively. Research limitations/implications: Special tools have diversification. They can not be taken into consideration in the database system owing to the tools have specific profiles. Therefore, it is difficult to encode by formal rules. Practical implications: The most commercial tool grinding software is the modular-based design and uses tool shapes to construct the CAM interface. However, it is very difficult for users to design new cutting tools. Utilizing the grinding processes to construct the grinding path of tools, and the search system of the database provides more flexible options to develop new cutting tools. Originality/value: The database and search system of cutting tools were presented in this paper. We can save time for production line change, tool design, and tool grinding by employing this kind of system. It also gives more convenience. That is, company's productivity and benefit can be improved.
