Investigating the CO2 laser cutting parameters of MDF wood composite material

Abstract

Laser cutting of medium density fibreboard (MDF) is a complicated process and the selection of the process parameters combinations is essential to get the highest quality of the cut section. This paper presents laser cutting of MDF based on design of experiments (DOE). CO 2 laser was used to cut three thicknesses 4, 6 and 9 mm of MDF panels. The process factors investigated are: laser power, cutting speed, air pressure and focal point position. In this work, cutting quality was evaluated by measuring, upper kerf width, lower kerf width, ratio between the upper kerf width to the lower kerf width, cut section roughness and the operating cost. The effect of each factor on the quality measures was determined and special graphs were drawn for this purpose. The optimal cutting combinations were presented in favours of high quality process output and in favours of low cutting cost.

Effect of CO2 laser cutting process parameters on edge quality and operating cost of AISI316L

“…For this laser system with 1.5 kW maximum outputs power the operating costs generally falls into the categories listed in Table 4. The operating cost calculation does not account for any unscheduled breakdown and maintenance, such as a breakdown in the table motion controller or PC hard disc replacement [17]. The total approximated operating cost per hour as a function of process parameters can be estimated by 2.654+1.376xP + 9.60x10 -3 xF.…”
