Abstract(s)
This study aims to develop a new jig holding system that is able to be controlled by a Computer
Numeric Control (CNC) installed on three-axis machining centers, which can drastically improve
the productivity in machining operations, enabling the machining of unparallel plans
in the same setup. An action research methodology was adopted for this work, which, through
a practical approach, intends to generate transferrable knowledge to other organizations
whose situations are like those in this study. Together, the practical actions and the knowledge
acquired create the changes needed for improving these processes. By conducting a case
study, it was observed that savings of about 40 % can be easily achieved for parts with
low geometric complexity. If the complexity of the parts increases, it is expected that these
savings can be even higher. The return of investment is less than 2 years, which is usually
affordable for enterprises. Through this study, it was possible to develop a new jig holding
system that can be attached to a three-axis CNC machining center and clearly expands its
functions and productivity. With this system, it is possible to work in different planes of
the part in sequence, as well as use a double-sided table for the jigs, doubling the production
batch each time the machine is loaded. Moreover, a list of key settings has been created with
the main requirements and recommendations to adopt this kind of production system, which
can be highlighted as the main research output.
