Measurements of considered shaft and its datum shaft of a stepped shaft.

Data from administration of the Genetics Concept Assessment as a pre and post test to students taking introductory genetics courses at six different post-secondary institutions in the United States between 2015-17.

These data are denoised signals processed by wavelet thresholding-based denoising. They are represented by a 2-dimensional matrix. Each row represents a vibration signal,and the first 45 rows belong to mormal rotor, the second contact-rubbing, the third unbalance and the final misalignment. Each column represents the length of data, 2048, or time, 1s.

Technical diagnostics is currently one of the most important factor of reliability and thus the operability of machines and machineries. The increasing reliability requirement is closely related to technological development which is accompanied by complicated equipment and products. This fact increases the demands for maintenance of machinery which must ensure an intensive use of the means of production and equipment. In addition, this must be used in the methods and means of technical diagnostics. The authors approached in article the sequence of steps applied in the framework of diagnostic analyzes of planetary gear machining center focusing on the running-in phase of the technical system. The tests were applied in two parts. The first type of analysis realized the trend diagnostic vibration measurements, acoustic emissions and assessment of the friction of wear particles Fe analysis for two types of gear oils (Madit PP-90 and X-220). Analysis of a part B applied the same diagnostic measurements, but only for one type of lubricants, industrial gear oil Madit X-220. In view of the high-frequency vibration measurements in both cases (analysis A and analysis B), at the end of a run-smooth surface it confirmed that all monitored dynamic parameters were below the level of set alarms. In view of the state of lubrication and friction in both cases it confirms that the second load of transmission oil exhibited a much better shape both in terms of thermal - oxidative degradation (oil and surface) and of the quantity of wear particles of Fe. The mechanisms for formation of the particles are relatively complex tribological processes; the particles are mostly products of adhesive and abrasive wear. Adhesive wear occurs when between the mutually moving surfaces there is not sufficient oil film, which is due to either a low viscosity oil or inadequate lubrication. Abrasive wear occurs most often when the abrasive particle gets between two mutually moving surfaces. The result of abrasive wear is a creation other particles that contaminate the oil. Realized experiments and measurements have been shown to influence the type of transmission oil to the operating characteristics of planetary gear machining center. For example, the oil with lower viscosity may have a problem with maintaining the lubricant film, which clearly leads to greater wear. A suitable viscosity is always ultimately manifested in increased heating of transmissions, caused by either excessive friction between components or by difficult running of gear shifting mechanism. Of course a huge impact on the properties of lubricants and oils is their type and composition of individual additives.

Attached files present a group of case studies to demonstrate applications of the developed metodology, DPCA, in coordinate metrology of various geometries. The examined cases include sculptured and free-form surfaces, as well as primitive geometric elements. Data and results are presented in Excel format. Three files are presented for each inspected geometry. The three files include: 1- Control Points of the desired CAD model 2- Point cloud captured from the fabricated product 3- The best transformation matrix obtained by DPCA registration of measured points.
