The big sized milling cutters are expensive tools and are not appropriate for small batches production. Making these tools more versatile, able to fit to different kinds of processes and shapes of the parts to be machined is a must. As well, cooling the cutting area is very important. The existing end-mill cutters are designed to feed internally with coolant only the teeth on the front side. The paper presents a concept of a modular tool, made of elementary disk cutters, able to be reconfigured to get different shapes and sizes. The main element of novelty the paper claims is the inner cooling system of the complex tool. The special design of the elementary milling cutters and of the shaft they are mounted on make the tool able to lead jets of coolant to every insert, no matter where they are placed, on the cylindrical or on the front side of the milling cutter. A network of channels drilled in the shaft and in the body of elementary milling cutters make this possible. The capability to splash with coolant under high pressure all the cutting edges do not depend on the number of teeth of the tool. Being delivered from inside the cutting tool, the coolant splashes directly on the contact surface between the inserts and workpiece, which makes cooling more efficient.

The most frequent workplace accidents in the industry are most of the times caused by the employer’s failure to fulfill their obligation to provide appropriate on-the-job training. Starting from this state of affairs, this paper analyzes the main cause of workplace accidents in the industry, which is the lack of training, or incomplete or inadequate training of employees, a situation indicated by the latest studies and the latest activity report of Labor Inspectorate. The solution identified by most employers was to use the online environment, this being the only way that allows the achievement of both of the aforementioned objectives at the same time. In this context, the paper identifies and proposes the use of the online environment, especially in the process of distance training of workers, giving them the opportunity to receive training documents, to analyze them, to electronically sign them and send them to the employer in electronic format. This proposal of supplementing the current legislation with the possibility of using the online environment in the field of occupational health and safety (OHS) also takes into account other categories of benefits that this solution brings, such as streamlining OHS and optimizing costs incurred in fulfilling these legal obligations.

In the recent years, the industry tends to an accelerated evolution in order to maintain the competitiveness on the profile market. As a response to this challenge, engineers and researchers have started to combine multidisciplinary knowledge with solutions provided by programming software so as to obtain immediate and reliable results on each step of a product development. The main advantage is highlighted especially for the optimization phases, when the using of the parametric tools is less time-consuming and the majority of issues of the developed product are solved from the first version of the project. This paper aims to present a case study of a parametric design and meshing in MSC Patran environment, using a programming solution in Visual Basic, of a part with a complex geometry from aerospaceindustry and also to accentuate the minimized risks from the design phase to manufacturing, with a review of the advantages and disadvantages.

Nowadays, the movement of Post-Modernism, which appeared in 20th century, influences the art and the design of products. It is considered that the investigation and the undermining, which construct the modern society, compel a traditional prioritization based on cultural values. Furthermore, today the main effect is the image as the users opt to purchase their products by the appearance that is more substantial than the usage. For that reason, the alteration of daily products is the cause of this paper so that the consumers feel confused by them. Namely the basic image of a product may be the same as or similar to an original object, but it may alter the use of it. The viewer should interpret the image differently such as his experience and his belief. In addition, the change of visual messages can be achieved by the complexity of geometry, the combination of objects and the modification of materials. This is defined by the movement of Unruly design that aims for offering a new aesthetic of products. Finally, the goal of this paper is to present a number of illustrative case studies, which ensure an appropriate interface relationship between the art and product design.

At metal drilling, at the beginning of the process, the cutting tool in the chisel edge zone, frictions and plastically deforms the material, and then enters in cutting. If the drill is entered smoothly in cutting with a special device, its life is increased. The paper presents how the electrical current at cutting is used for the evaluation of smooth entrance in cutting in comparison with classical cutting. These are demonstrated for 41MoC11 steel drilled with a set of 30 tools having 8 mm diameter.

During the process of drilling metals there are used cutting tools that can be acquisitioned directly from the producers, from distributors or from supermarkets. Because the offer is varied and there are different producers, the acquisition must be made after an economical analysis that includes experimental tests. The paper presents an innovative methodology of drills acquisition based on electrical current at cutting process. The researches were developed using HS 6-5-2 steel drills of 8 mm diameter, in two batches, acquisitioned from two different suppliers, at different prices. The drills were tested on 1C45 material using the same values for cutting parameters and because the electrical current at cutting is sensible to any imperfection of the tools, the batches were analysed from qualitative and economical point of view.

During the process of turning metals there are used cutting inserts that can be acquisitioned from different producers. Because the offer is varied the acquisition must be made after an economical analysis that includes experimental tries. The paper presents an acquisition methodology for metallic carbide cutting inserts and presents a case study.

Nowadays the customer requirements are in permanent changing and according with them the tendencies in the modern industry is to implement flexible manufacturing processes. In the last decades, metal forming gained attention of the researchers and considerable changes has occurred. Because for a small number of parts, the conventional metal forming processes are expensive and time-consuming in terms of designing and manufacturing preparation, the manufacturers and researchers became interested in flexible processes. One of the most investigated flexible processes in metal forming is incremental sheet forming (ISF). ISF is an advanced flexible manufacturing process which allows to manufacture complex 3D products without expensive dedicated tools. In most of the cases it is needed for an ISF process the following: a simple tool, a fixing device for sheet metal blank and a universal CNC machine. Using this process it can be manufactured axis-symmetric parts, usually using a CNC lathe but also complex asymmetrical parts using CNC milling machines, robots or dedicated equipment. This paper aim to present the current status of incremental sheet forming technologies in terms of process parameters and their influences, wall thickness distribution, springback effect, formability, surface quality and the current main research directions.
