The stylus system that is categorised in this group is the stylus system of micro CMM, which has a similar design with the conventional CMM probing system. As described in ISO 10360-1, the stylus system has a spherical stylus tip, a rod stylus shaft and a sensing element. These styluses also operate in contact mode.

1.1 UMAP Mitutoyo Stylus (1993-1999) Figure 2.1: construction of UMAP stylus system Mitutoyo UMAP stylus system was first developed by a group of researchers in 1993 to 1999 at University of Tokyo, Japan [1]. After that, this research has been continued by the Mitutoyo Research Centre Europe and was commercialised by the Mitutoyo Company [2]. There are three models of stylus system which are UMAP 103, UMAP 110 and UMAP 130. UMAP 103 consists of the smallest diameter of sphere stylus tip, which is 30 µm, a stylus shaft of 20 µm in diameter and 3 mm in length. On the other hand, UMAP 110 consists of a stylus …show more content…
By using the glass to metal sealing technology, a melted glass is mounted like water drop at the tip of Ni-Cr wire stylus shaft. The surface tension of the glass will form the sphere shape. The assembly process occurs in the vacuum technology. One of the reasons that Ni-Cr stylus shaft was selected in this design is because of the property’s affinity towards the glass is extremely high [4][3]. Other important properties of the UMAP stylus system are the ability to mount to the Mitutoyo Micro CMM. The repeatability of the UMAP 103 is σ= less than 0.1µm and has a measuring speed of less than 100µm/sec. The measuring range of the UMAP 103 is 245 x 200 x 200 mm, with a contact force of 0.15 µN to 10 µN and stiffness of 21kN/m. The UMAP 103 stylus system can also be removed, installed, and replacing the stylus easily by the
