Abstract A laser measuring instrument was installed in a
computerized numerically controlled (CNC) router, and an
automatic measurement system, which was developed in a
previous study, was used to automatically measure the cutting
edge profile of throw-away type straight bits without
stopping the CNC router. In addition to the abovementioned
system, in this study, an adaptive control program
based on experimental data was installed, and an
adaptive control grooving system that improved machining
accuracy and controlled the burr formation corresponding
to the progression of tool wear under processing was developed.
Verification experiments of this system were carried
out. The main results obtained are summarized as follows:
(1) the between-process method was adopted for this system,
and three types of processing methods (type 1, 2, 3),
which consisted of a combination of an up-milling surface
and a down-milling surface after processing, were investigated;
(2) from the results of verification experiments, type
2 and type 3 methods showed remarkable ability to improve
the machining accuracy and control the burr formation; and
(3) it was found that the system employing adaptive control
processing corresponding to the progression of tool wear in
grooving is very effective.
