Summary
Solid carbide drill wear can be correlated to measurable machining parameters when drilling graphite composite work material. The thrust force is found to be the leading indicator of wear with feed and speed having minor influence. Industrial drill wear limits are governed by the quality of the hole produced. The total depth of material removed is a convenient means of expressing the degree of drill wear permissible. An on-line monitoring system has been developed utilizing the computational power and low cost of the microcomputer. Development of sensors to retrofit existing equipment makes the system industrially feasible.
