This article focused on comparing of the properties of the two most used materials, Acrylonitrile-Butadiene-Styrene (ABS) and Polylactic Acid (PLA), in the Rapid Prototyping (RP) process using the Fused Deposition Modeling (FDM) method. The thin-walled components were manufactured by Zortrax M200 and DeeGreen 3D printer. Print settings and printer parameters are also mentioned in the article. The printed models were 3D digitized using the GOM ATOS Triple Scan II optical 3D scanner. Main section is focused on the analysis of individual components in the GOM Inspect software. Authors used this software to measure the individual distances. The last section of the paper focuses especially on the evaluation of obtained results in the form of tables and a chart.

Numerous industrial enterprises are forced to increase productivity if they want to stay competitive in the market. Therefore, there were performed many researches focused on possibilities of cost effective increasing the productivity. There were created advanced processes and new machining strategies, which could be improved by new cutting materials, advanced coatings and modified geometry. One of the cost effective methods to increase productivity is High Feed Machining (HFM). This method does not require high speed spindle (in contrast with High Speed Cutting -HSC). Moreover, it does not require any special devices or conditions. HFM can be performed on the modern machine tools. This article compares conventional milling and high feed machining of the reference steel materials -C45 by creating some basic shapes and features, such as horizontal and vertical surfaces, cylinders, grooves, etc. Results of the experiment could be applied to determine when HFM is advantageous and what advantages it brings about.

This paper addresses the uncertainty analysis in the case of a coordinate measuring machine. The main goal was analyzing, quantifying, and drawing conclusions on the influence of key factors and their interactions on the measurements’ uncertainty of the variable’s parallelism, angularity, roundness, diameter, and distance. In order to achieve this goal, a Random Factorial Design of Experiments was designed and implemented. It focused on the factors Stylus diameter, Step width, and Speed using three random levels each. For the solution of the experiment, an analysis of variance was used. The study was carried out on the coordinate measuring machine (CMM) ZEISS CenterMax. It was concluded that the interaction effects among Stylus diameter, Step width, and Speed were active at a confidence level of 95%. Besides, it was possible to estimate random factors‘ variance and their contribution to the total variation. Among the main effects, the Stylus diameter showed to be the one with the biggest influence. The paper also quantifies the influence in the measurement uncertainty, where the highest value of standard uncertainty belonged to the Stylus diameter in the evaluation of the variable’s angularity and diameter. Besides, the Speed factor was proved to have the biggest influence on the roundness’ measurement and evaluation.

The article is about manufacturing a component with a precision circular hole by Digital Light Processing (DLP) additive technology for inserting another part. The accuracy of the hole itself depends on the choice of production technology and the appropriate material. Deformation of the inner wall of the hole prevents correct insertion of the part - nut of trapezoidal threaded rod. This article analyzes the feasibility of manufacturing a component using Digital Light Processing (DLP) additive technology and the use of liquid resin „Proto GRY“ for the manufacture a component. Among additive technologies processes, digital light processing (DLP) is typically seen as the technology capable of reaching the highest standards in terms of part complexity and precision. DLP technology rely on the use of light, typically in the UV region of the spectrum (380 – 405 nm), to cure a photosensitive viscous resin. This resin, typically composed of epoxy or acrylic and methacrylic monomers, will polymerize and harden when exposed to light. As light shines on the vat to create specific shapes or patterns that compose each layer, a solid object can be formed and extracted from the otherwise liquid resin.

Industrial tomography is currently the fastest growing sector of non-destructive research. Until recently, the use of computed tomography in industry has been limited mostly to defects in materials due to lack of accuracy. Modern measuring machines combining metrology and tomography can extract information about the external geometry and volume of the part with high precision from a single scan. This article deals with the transmission gearing scanning, which is a functional component used in the mechanical transmission design. It is imperative that it does not contain internal defects that can largely render the transmission ineffective due to the strain caused by stress. The component is produced by Digital Light Processing (DLP) additive technology. The chosen production method ensures greater strength of the part. The part will be made of material call as „Proto GRY “on a FabPro1000 printer from the company 3D Systems, Inc. The production process of the model will depend on the change in the orientation of the part.
