LAB WORK:

To measure screw threads using a profile projector.
Items to be checked are:

-Outsidediameter
-tooth on the effective diameter
-flank angle
-pitch
-core diameter

-INTRODUCTION:
In the measurement process in one piece involved various means to monitor the conformity ofthe part specifications of the plane. Often, the pieces have narrow regions where it is difficult to access means necessary to involve experts in order to respond to the specifications of theplane.With the help of a profile projector can perform 2D measurements on the enlarged shadow detail area of ​​interest, with a magnification factor known. Activity metrological complementary to this processinvolves the preparation of the appropriate cuts, which are specified in the plane.For this purpose you can use circular saw, wire saw with diamond coating etc. It is very important to fix the samplein the cutting system to understand the area of ​​interest, the plane means, the geometric center of detail. Once the section is to polish and clean the surface of to remove the excesses inherent inthe cutting process.In parts elongated connector type, console, or low elastic stiffness that could suffer remaining deformations or changes in the area of ​​interest during the cutting process.Thesespecimens, stiffening its structure a liquid resin with good fluidity after 24h are ready for the cutting process.Before starting to measure is to devise a good system for mounting on the glass tableprojector profiles, to avoid possible motion.The dimensions measured are usually very small radii, areas with a chamfer finish or dimensions that refer to very narrow areas where access to the probetip ruby ​​of a machine metrological dimensional or other means is impossible.Direct measurement is possible, using the reading of the shift regles axes or also aided measurement specific software,...
