Can diamond wire sawing be used for photovoltaic silicon wafers?

This paper reviews recent research on diamond wire sawing of photovoltaic silicon wafers and compares it with the loose abrasive wire sawing process from a standpoint of sustainable manufacturing.

What is a fixed abrasive wire sawing process?

Li et al. [76, 77] recently proposed an analytical model for the fixed abrasive wire sawing process, which describes the relationship between the cutting forces and process parameters such as the feed rate, wire velocity, and contact length between the wire and the cut material.

Will a shift from free abrasive/steel wire sawing to diamond sawing take place?

A shift from free-abrasive/steel wire sawing to fixed-abrasive diamond wire sawing is expected to take place in the PV cell manufacturing industry, with 2018 being the anticipated pivotal point for market dominance.

What is the operating principle of wire sawing?

Operating principle of wire sawing processes Figure 3 shows the two wire sawing processes schematically [7, 8]. In loose abrasive slurry sawing (LAS), a thin steel wire is fed through a supply spool and wound on rollers multiple times at a constant pitch, and eventually wound up on a take-up spool at the exit end.

Is fixed abrasive diamond wire sawing a sustainable manufacturing alternative?

Concluding remarks In this paper, we reviewed fixed abrasive diamond wire sawing as a sustainable manufacturing alternative to loose abrasive slurry sawing of silicon wafers.

What is a macroscopic model of a loose abrasive wire saw?

A macroscopic mechanical model of the loose abrasive wire saw was developed by Liedke and Kuna , who investigated the effect of wire sawing process parameters and geometric factors such as the ingot size, wire length, and the shape of wire bow.
