This paper presents the employment of Design of
Experiments (DoE) as the prediction tool for the laser
micro-machining process. Laser internal micro-channels
machined using pulsed Nd:YVO4 laser in PMMA were
studied. The experiments were carried out according to 33
factorial Design of Experiment (DoE). In this paper the
input process control parameters were laser power, P; pulse
repetition frequency, PRF; and sample translation speed, U.
The channel width and the micro-machining operating cost
per metre of produced micro-channels were the measured
responses. The responses were adequately predicted within
the considered micro-machining parameters limits. For both
responses, quadratic polynomial regression equations were
constructed. The developed regression equations can be
utilised to find optimal micro-machining process
parameters within the studied process limits under
experimental and operational conditions.
