Gold, a commodity widely regarded as a leading safe haven asset, is enjoying one of its most impressive rallies this year thanks to a trade war that’s rapidly deteriorating.

The flaw in the systemShanks of tapered toolholders are ground to a fine finish within very precise, established tolerances, and are also threaded at the narrow end to accept a retention knob. The knob engages with the drawbar, which exerts a pull force that holds the toolholder firmly in the spindle.

Acoustic tweezers have recently raised great interest across many fields including biology, chemistry, engineering, and medicine, as they can perform contactless, label-free, biocompatible, and precise manipulation of particles and cells. Here, we present wave number–spiral acoustic tweezers, which are capable of dynamically reshaping surface acoustic wave (SAW) wavefields to various pressure distributions to facilitate dynamic and programmable particle/cell manipulation. SAWs propagating in multiple directions can be simultaneously and independently controlled by simply modulating the multitone excitation signals. This allows for dynamic reshaping of SAW wavefields to desired distributions, thus achieving programmable particle/cell manipulation. We experimentally demonstrated the multiple functions of wave number–spiral acoustic tweezers, among which are multiconfiguration patterning; parallel merging; pattern translation, transformation, and rotation; and dynamic translation of single microparticles along complex paths. This wave number–spiral design has the potential to revolutionize future acoustic tweezers development and advance many applications, including microscale assembly, bioprinting, and cell-cell interaction research.

DXF Transfer allows the operator to import the CAD image, select the desired features, and the WinMax CNC control automatically creates the program. The part program can be checked on the screen with Hurco’s verification graphics system, which includes 3D solid rendering of the toolpath with dynamic rotation and real-time tool display so that the part can be viewed from any angle without being forced to re-draw it.

BIG Kaiser’s EWE digital fine boring heads connect wirelessly to BIG Kaiser’s user-friendly smartphone and tablet app, making it easier to monitor and configure the head while assembling and running boring tools. EWE fine boring heads feature a digital display to show incremental movement of the cutting edge. To help operators manually adjust tools more accurately and repeatedly they get a visual cue, but there still is the possibility for errors because each time an adjustment is made, a measurement must be taken, requiring a manual step.

Renishaw’s Equator shopfloor gauging systems are being used to great effect around the world to measure a vast array of manufactured parts. They enable intelligent process control of manufacturing cells and lines by delivering highly repeatable, thermally insensitive, versatile and reprogrammable shopfloor gauging. Renishaw will demonstrate the Equator gauging system in use on a range of components and assemblies, including those for electric motors. Featuring Renishaw’s intelligent process control (IPC) software, the Equator system provides manufacturers with the functionality to automate process control and tool offset correction directly to CNC machines. The proximity of the Equator gauging system to CNC processes allows rapid measurement and process adjustment at the point of manufacture, avoiding time delays or relying on finished part (‘tailgate’) inspection. Available in two size variants – the 300 and the 500 – the Equator gauging system is unique in its design and method of operation.

Wroński referred to the Ukrainian experiences. After the Russian side introduced Pantsir, Tunguska or ZSU-class systems, the Ukrainian aviation started to suffer from significant losses. Moving the aviation away from the threat – 8-20 kilometers away in this case – shall be viewed as a proper response. Tactical side of operations also underwent a major change. The Ukrainian helicopters maintain radio silence to avoid detection, they are flying in loose formations and with CSAR support.

Machining high-value, complex components requires additional quality control steps to ensure parts are produced correctly. The last thing a shop wants to see is an expensive part making it all the way to the quality control department before realizing it is out of spec and needs to be reworked or even scrapped.
