Frame saw machine is one of tools that used to process dimension stone. The velocity fluctuation traditional feed drive system (FDS) lead excessive wear diamond particles. dynamic performance the FDS has time-varying characteristics during processing stone with a large material removal rate. In this paper, novel was proposed. Firstly, modeling set up on account lumped parameter method (LPM). Th...

Diamond-wire-sawn (DWS) technology has been widely used in the photovoltaic industry. When using HF/HNO 3 /H 2 O acid etching solution for texturing of DWS multi-crystalline silicon(mc-Si), aid additive is required to improve reactivity mc-Si surface solution. It also needs enhance nucleation and uniform growth surface. This paper proposes a non-metallic texturing. Sodium polyacrylate added red...
