The application of a microcomputer for measurements of two-dimensional surface roughness (General construction of the system, measuring method and measured examples)

An automated system using a microcomputer for a two-dimensional surface roughness measurement with a stylus is developed. The block diagram and flow charts for the surface roughness measuring method are described, together with the measured examples. It is found that this programmable system obtained at a low price is very useful for such a measurement and for data processing In the Appendix Assembler subroutine programs for measurement and control using an 8 bit microcomputer are given.
