Abstract: A developed profilometer was designed and manufactured to determine different mechanical profiles depending on tactile sensing technique. The basic concept of the profilometer work depends on direct contact between the stylus tip and the measurand part. The design is robust and suitable to measure the selected part. The surface profile of a cam shape was measured by using this profilometer. The obtained profile has a big match with the actual dimensions of the measurand part. Cross correlation function also was studied to find the best matching between profiles.
