Purpose The purpose of this paper is twofold: first, a case study on the application of lean production principles in a manufacturing facility is presented to demonstrate the impact of frequent and systematic use of a Kaizen event on quality and delivery performance. Second, the detailed description and analysis of the Kaizen event and its impact are provided, including a comprehensive analysis of the role of Kaizen events on employee participation and motivation. Design/methodology/approach The study utilizes a Kaizen event’s case study data with the help of various waste detection and elimination tools and techniques. Changes in overall productivity along with potential long-term improvements in the delivery process are also analyzed and documented. Findings Pre- and post-quality measures are provided to demonstrate the results of the event on the production quality and on the performance of the overall manufacturing processes. Qualitative findings regarding performance measurements and the impact on the employees are reported. Research limitations/implications The Kaizen team applied analytical techniques to one manufacturing site in North America of a company that has a manufacturing presence in 20 different countries. Originality/value Kaizen studies involving packaging operations are quite limited. This study fills this gap by detailing the Kaizen event implementation in a packaging delivery and dispensing systems manufacturer for the cosmetic industry. The implementation of this Kaizen event is detailed along with the data and techniques utilized for process improvement. The study also reports findings regarding the impact of the Kaizen event on employee participation.


Lean concepts play a fundamental role in the promotion of continuous improvement in the workplace. This chapter seeks to assess the impact of Kaizen events on an organization's bottom line, in the case of Single-Minute Exchange of Dies (SMED) that is a system for dramatically reducing the time it takes to complete equipment changeovers. In this case study, SMED was used in combination with other lean tools such as 5S and standardized work in a bid to promote continuous improvement of the “flawed” operations that occur in a world-class manufacturer plant. This analysis is critical in determining whether the path to achieving continuous improvement process for the team in the organization can be achieved through the use of SMED. The results have shown that a lean strategy like SMED, coupled with other lean strategies like 5s and TPM, plays a fundamental role in reducing process inefficiencies in the plant.

The impact of 3D Printing on automotive parts is investigated. 3D printing is an additive manufacturing technology to rapidly create prototypes by laying down a broad range of material onto successive layers of surfaces. In the automotive parts generally metal or alloy materials are used in the manufacturing. In this research we tested effect of 3D Printing on different automotive components. For the testing purpose we used Front Hub, Rear Hub, Knuckle, Calliper, CAM (engine part) and Steering pedal. After manufacturing in FDM printer using PLA material, the different properties were checked, and compare the result of existing manufactured components with the 3D printed one. The results showed that the 3D printed components having lesser weight up-to 35% to 40% with better geometric finishing. It also allows the complex geometric in the manufacturing process.

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

AbstractWhilst lithopanspermia depends upon massive impacts occurring at a speed above some limit, the intact delivery of organic chemicals or other volatiles to a planet requires the impact speed to be below some other limit such that a significant fraction of that material escapes destruction. Thus the two opposite ends of the impact speed distributions are the regions of interest in the bioastronomical context, whereas much modelling work on impacts delivers, or makes use of, only the mean speed. Here the probability distributions of impact speeds upon Mars are calculated for (i) the orbital distribution of known asteroids; and (ii) the expected distribution of near-parabolic cometary orbits. It is found that cometary impacts are far more likely to eject rocks from Mars (over 99 percent of the cometary impacts are at speeds above 20 km/sec, but at most 5 percent of the asteroidal impacts); paradoxically, the objects impacting at speeds low enough to make organic/volatile survival possible (the asteroids) are those which are depleted in such species.

AbstractA large amount of CO has been detected above many SL9/Jupiter impacts. This gas was never detected before the collision. So, in our opinion, CO was released from a parent compound during the collision. We identify this compound as POM (polyoxymethylene), a formaldehyde (HCHO) polymer that, when suddenly heated, reformes monomeric HCHO. At temperatures higher than 1200°K HCHO cannot exist in molecular form and the most probable result of its decomposition is the formation of CO. At lower temperatures, HCHO can react with NH3 and/or HCN to form high UV-absorbing polymeric material. In our opinion, this kind of material has also to be taken in to account to explain the complex evolution of some SL9 impacts that we observed in CCD images taken with a blue filter.

AbstractHydrogen cyanide polymers – heterogeneous solids ranging in color from yellow to orange to brown to black – may be among the organic macromolecules most readily formed within the Solar System. The non-volatile black crust of comet Halley, for example, as well as the extensive orangebrown streaks in the atmosphere of Jupiter, might consist largely of such polymers synthesized from HCN formed by photolysis of methane and ammonia, the color observed depending on the concentration of HCN involved. Laboratory studies of these ubiquitous compounds point to the presence of polyamidine structures synthesized directly from hydrogen cyanide. These would be converted by water to polypeptides which can be further hydrolyzed to α-amino acids. Black polymers and multimers with conjugated ladder structures derived from HCN could also be formed and might well be the source of the many nitrogen heterocycles, adenine included, observed after pyrolysis. The dark brown color arising from the impacts of comet P/Shoemaker-Levy 9 on Jupiter might therefore be mainly caused by the presence of HCN polymers, whether originally present, deposited by the impactor or synthesized directly from HCN. Spectroscopic detection of these predicted macromolecules and their hydrolytic and pyrolytic by-products would strengthen significantly the hypothesis that cyanide polymerization is a preferred pathway for prebiotic and extraterrestrial chemistry.

Crushed and statically compressed Madagascar graphite that was explosively shocked at 425 kb by means of a planar flyer-plate is characterized by a black zone extending for 2 to 3 nun below the impact plane of the driver. Beyond this point, the material assumes the normal gray color of graphite. The thickness of the black zone is identical with the distance taken by the relaxation wave to overtake the compression wave.The main mechanical characteristic of the black material is its great hardness; steel scalpels and razor blades are readily blunted during attempts to cut it. An average microhardness value of 95-3 DPHN was obtained with a 10 kg load. This figure is a minimum because the indentations were usually cracked; 14.8 DPHN was measured in the gray zone.
