Taylor-Hobson Talysurf-10 surface

The counterface topography was analysed on a Rank Taylor Hobson Talysurf instrument linked to a VAX computer. Surface profiles were analysed at intervals of 1.554 over a traverse length of 3.8 mm to give some 2445 data points. All the height readings were input as positive numbers relative to an arbitrary datum. They were then... 

The surface roughness of the machined workpiece is measured using a Taylor-Hobson Talysurf-10, while the tool wear has been measured using a normal toolmaker microscope. The temperature distribution in the vicinity of the cutter is indicated using an infrared camera AGA Thermovision System 680/102B. 

Surface profiles of both sides of a calendered and an uncalendered sheet were recorded with a Talysurf 5 instrument (Rank Taylor Hobson, England), and are reported in Fig. 13. The surface is different in each case, but the bulk conductivity is not significantly altered. The pressure applied to the electrodes within the cell has not changed the surface profile of the sheet for the calendered sample. Although a difference is observed for the uncalendered sample, the surface is not as smooth as that of the calendered sheet after pressure is applied. 

Figure 17.4 shows the surface map of a Bionext dry membrane recorded in a Taylor Hobson Form Talysurf Series 2 profilometer.

Surface profile measurements were made by means of a Rank Taylor Hobson Form Talysurf with a 0.2-p,m diamond-tip probe in all the various planes and directions in these planes, i.e., LT, TL, LS, SL, ST, and TS. The instrument created a line scan of a real surface by pulling the probe across a predefined part of the surface at a fixed scan rate of 1 mm/s. All traces were of length 8 mm, generating 32,000 points with a sampling rate of 0.25 p,m per point, except for the SL and ST directions, which, because of the plate thickness, were limited to 2-mm... 

The surface roughness of the ring and liner samples was measiued before and after the test series by using a Taylor-Hobson Form Talysurf PC diamond stylus instrument, see selected parameters in Table 1. 

The roughness of the newly cut workpiece surfaces was measured using a Form Talysurf 50 profilometer (Rank Taylor Hobson). Arithmetic average surface roughness (Rj) values were recorded at five different locations along the length of the workpiece and averaged to obtain a mean value for the Ra- This mean Ra value is reported.
