Presented article is focused on CW004A cooper surface topography evaluation disintegrated using pulsed water jet enhanced by ultrasound. Primary objective was identification and describing of disintegration pulsed water jet areas effect on material with usage of round orifice nozzle. Twenty-five samples were manufactured with variable traverse feed speed vf = 0.1-20.0 mm.s-1 , to observe and asses areas of disintegration. Surface topography signs were evaluated using surface roughness parameters Rz [μm], Rp [μm], Rv [μm], mass material removal Δm [mg.mm-1 ] and volume material removal Vm [mm 3 ]. As a result of experimental research were determined three basic areas of pulsating water jet effects on disintegrated surface.

The article deals with design and design of a thin-walled heat sink for the robot control system, the measurement of the transverse roughness of the touch surfaces and the programming procedure in Autodesk Inventor 2019 software. In this software, a design of the 3D model of the heat sink generated based on power supply and NC code generation for the Fanuc control system. The production it-self carried out on the CNC Vertical Machining Center Pinnacle 2100 with this control system. The longitudinal surface roughness was measured with a Mi-tutoyo SJ 400 dredger and the measurement result was the maximum Ra = 0.69 μm and Rz = 4.1 μμm.

“…Zelenak et al [9] have obtained visualization of pulsating and continuous waterjets by using the PIV processing algorithms, with an aim to obtain waterjet geometry and velocity distribution. Lehocka et al [10,11] have studied changes in surface layer and strengthening in subsurface layer of the copper CW004A and brass CW614N machined by pulsed waterjet. eir research result indicates that the pulse waterjet has a great advantage contrasted to the continuity waterjet.…”

e ultrasonic vibration is used to enhance the capability of the abrasive water micromachining glass. And, the ultrasonic vibration is activated on the abrasive waterjet nozzle. e quality of the flow is improved, and the velocity of the abrasive is increased because of the addition of the ultrasonic energy. e relevant experimental results indicate that the erosion depth and the material volume removal of the glass are obviously increased when ultrasonic vibration is working. As for the influence of process parameters on the material removal of the glass such as vibration amplitude, system pressure, distance of the standoff, and abrasive size, the experimental results indicate that the system pressure and vibration contribute greatly to the glass material removal. Also, the erosion depth and the volume of material removal are increased with the increase in the vibration amplitude and system pressure. ere are some uplifts found at the edge of erosion pit. en, it can be inferred that the plastic method is an important material removal method during the machining process of ultrasonic vibration-assisted abrasive waterjet.
