Rapid machining means the extreme reduction of the machining lead-time
required in completing a product from the blank shape. One of the ways
in which machining lead-time could be reduced drastically is by avoiding
too many setup changes. This paper presents a new machining method to create
a groove with sharp corner on adjoining surfaces in one setup. Grooves with
sharp corner (GSC) on adjoined curved or overhanging surfaces are a present
impossible to manufacture by conventional machining in one setup or even by
the existing numerical control (NC) machining method especially if it is
adjacent to the obstruction. The obstruction tends to hamper the flow of
machining operation, thereby requiring two or more setups as well as additional
expensive fixture to machine such product.
In the study, the GSC on adjoined curved or overhanging surfaces will be
manufactured by 6-axis control milling using a non-rotational tool with the
application of ultrasonic vibrations (USV) in one setup. The study also
describes the machining method as well as the development of software for
6-axis control milling and the effect of ultrasonic vibrations in multi-axis
machining. Based on the experimental results, the effectiveness of the new
manufacturing methods as well as the developed CAM software has been
experimentally confirmed in the study.
