2020-3-6Laser micromachining is a technique known to deal conveniently with hard-to-machine materials [] with high precision [] and has no concerns over the tool wear or machine vibration issues [] However nanosecond (ns) laser thermal ablation [4 5] is often accompanied by excessive heat that may create a heat affected zone (HAZ) leading to a few adverse effects such as oxidation edge
2020-1-3serving as debris containers The effects of microstructure on wear behaviors of the SLM fabricated SS316L samples under dry conditions were also studied by Yang et al (2019) Severe damage was found in the Sz sliding direction after the scratch tests due to the slipping of columnar structures
Laser hazards control measures: 3- Administrative control: • Knows the limitations of device output • Ensures laser maintenance beam alignment and calibration of the laser device • Supervises medical surveillance and incident reporting • Keeps a log of recorded laser use and parameters employed 48
2016-12-16Figure 3 – Rotation of the AVR laser shows idler angular alignment by comparing two points along the belt edge Much of the world estimates the main resistances with a single overall friction factor based on history though each of the main resistances is affected differently by the specific material design and construction details
1 Wear debris analysis is essential to effectively gauging machinery life When machine components begin to wear the evidence can usually be found in the lubricant flowing through the machine For example as parts undergo sliding fatigue or creep pieces of metal will begin to break off the components and show up as wear debris in the lubricant
The laser shaft alignment technique is based on physics criteria with a reflected beam principle where the laser is attached on one-shaft and projects its beam to a detector which is attached on the second shaft [2] Effects of coupling misalignment on vibrations of rotating machinery dynamic balancing wear debris 2001
Dry Friction Between Laser-Patterned Surfaces: Role of Alignment Structural Wavelength and Surface Chemistry Tribol Lett 9 193–202 (2013) [Google Scholar] Rosenkranz A Reinert L Gachot C Mcklich F Alignment and wear debris effects between laser-patterned steel surfaces under dry sliding conditions Wear 318 49–61 (2014)
2 3 Laser Texturing The parameters to laser texturing the regions shown in Figure 4 were adopted considering the results obtained by Ramesh et al [] who concluded that the dimple depth should be near the film thickness in the interface die-blank In this work is assumed to be 30 μm for two textures and 150 μm for the other two to evaluate opposite conditions to supplying solid lubricant
Wear debris contaminates the bearings increasing drag and reducing life Accumulated debris shorts the commutator increasing current and resulting in motor failure Some organizations take necessary precautions in material selection and coatings that permit brush motors to

The present invention discloses methods and apparatuses for substrate singulation Embodiments of the present invention comprise cryogenic-assist scribing or cutting mechanism for debris reduction preferably cryogenic-assist laser scribe or cutting controlling mechanism for debris flow and redeposition during laser process and integrated dry debris removal scribing process with breaking
2019-1-28laser Laser pulley alignment systems are now well established in the sheave alignment field and have proven themselves in greatly reducing downtime and the manpower needed to do the alignment while simultaneously achieving far greater accuracy This results in significant labor savings and increased production uptime
Gruppenleitung: Dipl -Ing Leander Reinert Ziel der „Surface Engineering" Gruppe ist es Oberflchen so zu gestalten dass sie fr den jeweiligen Einsatzbereich optimale Eigenschaften besitzen Dazu werden verschiedene Methoden der Oberflchenbearbeitung von der Nano- bis Makroskala verwendet um die Oberflcheneigenschaften in verschiedenen Anwendungsgebieten gezielt beeinflussen zu
2016-1-28Additionally all laser-treated samples had lower wear rates in comparison to the unpatterned reference [24] Gachot et al investigated the influence of the pattern orientation for stainless steel surfaces that were treated by direct laser interference patterning (DLIP) The authors concluded that the role of alignment is of utmost importance
If the base where the laser head is mounted on is slightly bent if there is some debris between the laser head and the base or if the laser head is mounted with more than Nm screwing down can lead to a bending of the laser housing which affects performance Please make sure that both sides (bottom face of the laser and the table) are clean
Alignment effects were studied by means of a newly developed positioning method Abstract In this experimental study periodic line-like patterns with different periodicities (5 9 and 18 m) were fabricated by laser-interference patterning on stainless steel samples (AISI-304) and on 100 Cr 6 steel balls

2019-9-9laser to create the target shape on the cornea B STAR S4 IR Excimer Laser System The STAR S4 IR Laser System is a 193 nm excimer laser system that delivers spatially scanning ultraviolet pulses of variable shape and size on to the cornea Pulse shapes may be circles of variable diameter or slits of variable width and orientation The
2020-8-14Soft foot is one of the most prevalent conditions found in rotating machinery This condition if not corrected makes an alignment job much more difficult and sometimes impossible If the internal alignment is not correct the external alignment will not matter
Fretting is a relative motion with a small amplitude between two oscillating surfaces Depending on the relative displacements and the normal load different sliding regimes can be identified: partial-slip and gross-slip regimes [20 21] Fretting damage mode depends on sliding regimes leading to cracking under partial-slip (lower amplitude) and wear under gross-slip (higher amplitude) conditions
This is considered normal and acceptable wear When there is an imbalance or non-uniform tolerances between part surfaces or the wrong materials or components are used the situation arises for premature wear Poor installation poor maintenance practices and

Laser Shaft Alignment| GO Wind| Wind Turbine Alignment By James Pekarek on February 18 2016 Precision alignment of the generator to the gearbox in a wind turbine (the high speed shaft) is critical to proper operation 60 percent of wind turbine downtime is related to drive train failure: gearbox generator main shaft and their associated
2 Pulley bearing wear Appearance: With the engine off and the belt removed manually rotate the pulley If you notice noise resistance or roughness the problem is likely to be pulley bearing wear Cause: Defective bearing and/or pulley Solution: Replace the complete tensioner Do not attempt to replace a worn pulley in a used tensioner assembly but always replace the entire tensioner

2017-12-15Nevertheless there are some key differences between automating EDM and automating other machining processes as Lagenhorst explained: "A lot of milling applications don't need stainless steel hardened tooling to hold the workpieces because you're running a water-soluble coolant on the machine " he said
3 Laser and pyrometer alignment Laser alignment On an optical table couple a focusing unit with the fiber optics that convey the high-power laser beam to the laboratory NOTE: In doing so pay maximum attention to avoid the formation of kinks in the fiber optics which may result in
Alignment eye wear: This type of eye wear is used for low power visible laser beams Alignment eye wear should not be worn during the operation of high power or invisible laser beams Instead safety eye wear that provides adequate protection should be worn Make sure that there is no electromagnetic interference between the laser equipment
