The purpose of this research was to create and design a methodology for new product evaluation with an interest in the affects that they could have on form and helical grinding. The design uses a relatively small and commonly available grinding machine so that testing could be done without need for an expensive helical grinding machine typical of that utilised in industry.
The grinding machine is a large apparatus, and the seated carver holds the jade while using tools of various shapes. The flexible-shaft engraving machine is small, portable, and has a handheld electric-powered rotary tool with a flexible drive (Michaelson et al., 2016), which makes it convenient to change different grinding heads (figure 3).
