This paper presents a new in-process measurement system for surface roughness with optics-fibre. In this system, the changes of distance between the fibre probe -and the workpiece surface due to the change of workpiece diameter, the geometric error of the guideway and the vibration of the spindle parts can be compensated. Tests under different cutting conditions show that the factors that affect the machined surface roughness in cutting aluminum alloy with natural diamond cutting tools are mainly the built-up...

This paper presents a new in-process measurement system for surface roughness with optics-fibre. In this system, the changes of distance between the fibre probe -and the workpiece surface due to the change of workpiece diameter, the geometric error of the guideway and the vibration of the spindle parts can be compensated. Tests under different cutting conditions show that the factors that affect the machined surface roughness in cutting aluminum alloy with natural diamond cutting tools are mainly the built-up edge and the vibration of cutting system. It is also shown that the variation of machined surface roughness due to tool wear can be identified and three different stages of tool wear can be monitored by detecting the change of machined surface roughness when cutting steel No.45 with high speed steel tools.

Based on large amount of experiments, a new in-process measurement system for the surface roughness with optics-fibre has been developed successfully. By this system, an optical fibre sensor is utilized to illuminate the workpiece surface and to detect the intensity of the reflected light. Signals coming from the sensor, through photodetector, pre-amplifier, low-pass filter and A/D convertor, are sent to a single chip micro-computer 8031. This system can display the roughness parameter Ra in digital. To solve the problems occuring in the cylindrical grinding process, such as the grinding fluid, circumstance light, changes of workpiece diameter and design of measurement device, the author presented some new ideas and measures.
