This paper presents a new machining method that efficiently cuts
overhanging curve grooves on wall surfaces without causing a
collision between the tool and the workpiece. It also describes the
development of software for 6-axis control grooving and the effect
of applied ultrasonic vibrations (USV) in cutting overhanging grooves
(OHG). In general, rotational tools are used to produce grooves, thus
resulting in long circular arc segments at the cutting end points, as
well as placing restrictions on the manufacture of grooves with
continuous change in curvature, while ensuring that they do not overshoot
the side clearance angle of the cutting edge with the groove. The study
aims at machining OHGs presently impossible to machine by conventional
methods. From the experimental results, it was found that the new
machining method, which is 6-axis control cutting using a non-rotational
tool with the application of USV, is capable of cutting an OHG on wall
surfaces correctly.
