“…Laser milling is fast emerging as an important technology for material micro manufacturing. Compared to other competing methods, such as micro electrical discharge machining, laser milling is the most versatile method of milling or micro texturing all types of materials [1][2][3][4][5]. An important advantage of the laser micromachining method is the ability to process dielectric materials, unlike EDM method.…”

“…As well as in traditional milling, laser milling technology can be implement in layer-by-layer material removal technology with constant tool penetration into the work-piece body and ability to changing of layer thickness to be removed [6]. Precise material removal is possible due to the phenomenon of cold ablation, consisting in the rapid evaporation of laser-illuminated material [3]. It is well known that short pulse, usually pico and femtosecond lasers are used for laser micromachining technology.…”

The article presents the problem of planning the laser beam trajectory for the laser micromachining process. The article concerns on the ablative laser micromachining issues. Different effects of laser beam trajectory on pocket geometry in laser micromachining were investigated. The results of experimental tests are presented. Based on the research, potential causes of different effects of the laser beam for various trajectories were formulated. Several different types of trajectories for the assumed shape were developed for the purposes of the research. Laser micromachining was performed with fixed parameters of the laser device using different trajectories. The article indicates the significant impact of the laser beam trajectory on the effect of interaction on matter during the laser milling process, which is not often mentioned in scientific reports. The article presents the basic geometrical measurements indicating the need to determine the leading of the laser beam. Studieswere conducted using the microscopic observation methods and interferometric methods for estimating the surface condition. The article indicates the need for extensive research focusing on the mechanism of the impact of the laser beam scan strategy on the effect on the material during ablative laser machining. The article summarizes the analysis and discussion of research results.

“…In scientific literature, there are an increasing number of papers related to laser processing of elastomeric and generally polymeric materials [ 1 , 2 , 3 , 4 ]. Laser microprocessing of elastomeric materials [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ] is an alternative to lithographic methods; it belongs to direct methods, using the sources of laser radiation, usually: CO 2 (wavelength 10.6 μm—medium infrared) and Nd-YAG (consecutive wave harmonics: 1064, 532, 326, and 266 nm—from near infrared to ultraviolet), also including ultrashort pulse lasers.…”

Elastomers are used as construction materials in numerous industries, and in particular the biomedical industry, mechatronics, electronics, the automotive industry, and chemical devices. The paper presents the results of tests involving the effects of microprocessing of elastomeric materials using a UV laser emitting picosecond pulses. In particular, it presents an analysis of the influence of the parameters of processing on its efficiency. The paper provides a recommendation of the most advantageous processing parameters for materials such as polyurethane and silicone (MVQ). The authors see prospects for the use of the developed technology in the techniques of sealing and microfluidisation. The final part of the paper presents examples of surface structures generated on elements made of artificial materials and the results of tests involving reduction of friction resistance of sealing rings in a pneumatic actuator.

“…Constantly evolving industry requires the development of increasingly new construction materials. Even the latest construction materials can be modified in a way that its designers did not anticipate [1][2][3][4]. Requirements for the quality of the surface of materials used are one of the most important selection factors in many different technological processes -e.g.…”

“…Laser devices are characterized by different properties of the generated laser beam that affects the surface of a workpiece [5][6][7][8]. Particular attention should be paid to laser devices giving the possibility of using the phenomenon of cold ablation, which requires high energy and ultra-short time of impact on the material [4].…”
