This article proposes a flexible surgical robot featuring strong magnetic steering achieved by hemispherical magnet array actuation, and high‐accuracy ultrasonic position sensing beacon total focusing method (b‐TFM). The with is described its parameters are optimized through finite element analysis to increase the field for actuation. strength at 100 mm same mass as cylindrical about 1.8 times higher than that of magnet. Using exhibits capability agile navigate along predefined trajectory....
Laser cladding repair is an advanced technology for repairing Invar alloy moulds; however, the influences of various processing parameters on quality moulds have yet to be determined. To explore optimisation laser parameters, analyses geometric features and microstructure layer were conducted. First, different powder feeding rates scanning speeds dilution rate substrate investigated by establishing a mathematical model power attenuation. Next, analysed. Finally, evaluated. At 2300 W, speed 3...
The laser power bed fusion (LPBF) forming process introduces heat accumulation and variations in powder layer thickness, which can destabilize the melt track reduce surface quality. This phenomenon is especially more serious early printing stage. To tackle this stability problem, we proposed a novel approach optimizing parameters on layer-specific basis. At first, numerical database was constructed through set of simulations. Then, neural network prediction model trained based database....
Purpose The manufacturability of extremely fine porous structures in the SLM process has rarely been investigated, leading to unpredicted manufacturing results and preventing steady medical or industrial application. research objective is find out limitation key processing parameters for printing so as give reference design planning. Design/methodology/approach In metallic AM processes, difficulty geometric modeling with pore sizes less than 350 μm exists. selective laser melting (SLM) To...
Purpose The objective of this study is to investigate the feasibility using selective laser melting (SLM) process print fine capillary wick porous structures for heat pipe applications and clarify interrelations between printing parameters structure functional performance form guidelines design preparation. Design/methodology/approach A new toolpath-based construction method adopted prepare with pores in SLM process. This uses physical toolpath profile associated directly define slices...
Manufacturability analysis is a critical step before manufacturing to reduce costs and risks. It used widely in conventional (CM) processes. However, the best of our knowledge, there no natural method evaluate manufacturability additive (AM) processes that have more uncertainty-derived risks than CM A clear definition AM has not been established, standard check whether component manufactured successfully by an process, particularly for porous complex components. This study introduces...

It is essential to control the heat generated in cutting zone order ensure workpiece quality after grinding. This article deals with an investigation using graphite and hexagonal boron nitride as solid lubricants reduce friction thereby improve surface integrity of Ti-6Al-4V alloy. The polymer-based lubricant coating wheels have been prepared. Grinding experiments conducted study effect on grinding temperature while Ti-6Al-4V. Results indicate that there a considerable improvement...
