Abstract:

Stone chisels produced by blacksmiths which are made using leaf spring steel are often too brittle or fragile so that when they are used, they often occur in the form of cracks and breaks. This study aims to determine the appropriate hardness level for stone chisels. The process is carried out by comparing the hardness level of stone chisels that have been used but still in good condition and those that have been damaged. Broken stone chisels have a high adequate hardness compared to good stone chisels so that damaged stone chisels can be reconditioned to get the right rock chisel hardness. He

Abstract:

Three chisels (Fig. 1), excavated by Woolley (1934) in the 1920s from an Early Dynastic III grave at Ur, and now in the British Museum, were believed to be made of solid gold. Recently, however, it was noticed that the gold surface was blistering in places, revealing coppery coloured metal beneath, suggesting that they were gilded.The chisels were from a very rich grave (PG 800), known as “the Queen's Grave”. It is attributed to Queen Pu-abi (in the original excavation report her name was mistakenly transcribed as Shub-ad) and dated to c. 2600 BC. Five chisels U. 10429–33 were found with a gol

Abstract:

In the fast-paced period, human desire to produce and compete quickly, efficiently and economically, became the basis for the development of tools and machine tools, the competition provided the main motivation in making machine tools that have accuracy, accuracy and precision, so as to make shape in accordance with the design (model). So in this case what should be considered is how to choose and determine the tool material to be used on a lathe, because it can affect the level of wear on the tool eye itself and the fineness or surface roughness that will be generated can be controlled visual

Abstract:

Resource efficiency and circularity in the context of sustainability are rapidly gaining importance in the steel industry. One concept regarding circular economy is “repurposing”. In the context of this work, worn-out machine circular knives are used to produce new chisels for woodturning. The chisels can be extracted parallel or perpendicular to the rolling direction of the primary production process, resulting in an associated carbide orientation of the repurposed tool. The rolling direction, and therefore carbide alignment, will influence the wear resistance and the thermophysical propertie

Abstract:

The energy shares occurring in the chiselling process were investigated in order to increase the productivity of the manual destruction of concrete. Apart from the influences of notch energy and cleaving energy, the energy loss due to friction forces was considered. As a result two new chisel forms were developed as a combination of sharp cutting edge and steep wedge. The effectiveness of these chisels was tested under experimental conditions as well as under reality conditions. It was found that the application of lateral tips at the chisel leads to an improved processing performance.

Abstract:

In this work, the vulnerability of standard PDC bits was established when conducting wells in difficult mining and geological conditions, in particular, with frequent layering of rocks with different hardness. The use of adaptive TerrAdapt chisels, which automatically change the depth of cutting and the aggressiveness of the chisel, is proposed in Russian deposits with frequently alternating rocks. These bits can be combined with overhead dampers if the dynamic coefficient is in the critical range. This solution will improve the technical and economic performance when drilling wells.

Abstract:

23 popular woodworking tool handle designs were collected to develop a reference visual catalog. Survey data was collected from 19 male craftsmen (11 carvers, 8 carpenters) regarding their most frequently used tools along with recommendations on handle designs suitable for these tools. Opinions were also collected regarding the most “liked” and “disliked” handle designs on the catalog. Subjective preferences and recommendations of handle designs for the most frequently used tools were also collected from a group of 58 undergraduate students of Design (41 male, 17 female).

Abstract:

The extraction of fossils by the use of chisels, hammers, and picks is probably the oldest of the methods dealt with in this volume. One must also admit that it may be the most tedious and time consuming method considering the more recent applications of power tools. Yet, exacting as it is, one has only to visualize the exquisite craftsmanship displayed in the sculptures of antiquity to realize the potential of these hand tools.

Abstract:

Chashkinskoye Lake is the Kama river palaeochannel. More than 20 archaeological sites are known on its eastern shore. They refer to the Mesolithic, Neolithic, Chalcolithic and Middle Ages. We divided all the tools that could be used for fishing in the Stone Age, into the tools directly and indirectly indicative of the development of fishing. We refer to the direct signs - the finds of sinkers and ice-splitting tools. We believe that the indirect signs include finds of axes, adzes and chisels that could be used to make boats. To this group we also include liners of composite throwing tools that

Abstract:

It is found that service life of Russian-manufactured ploughshares is determined by ray-shaped wear and abrasion of a deepening part of plough-point, but service life of imported components is determined by wear of cutting-blade parts of the frame. Some kinds of one-sided chisels wear can be repaired and do not cause their rejection.

Abstract:

Hand-held mechanical tools used in paleontology range from Jackhammers to high speed grinders. They operate by impact or rotary motion and are powered by air, gasoline, or electricity. These labor-saving devices are used in addition to, not as replacements for, hand tools such as awls, pin vices, chisels, and picks for the collection of and the removal of matrix from fossils.

Abstract:

The literature relating to the discovery and recording of the Siloam Tunnel is reviewed and the most recent scientific dating analysis is described. A date of 700BC or before for the tunnel is now almost certain. A discussion of the technical terminology in the tunnel inscription leads to the conclusion that the workmen who excavated the tunnel probably used picks, or axe like implements, rather than chisels.

Abstract:

Copper flat axes of the Szбkalhбt type are a fairly common type of tools in the contemporary withstages Trypillia BI—II, CI cultures of Central Europe. These tools are characterized by asymmetry of the profile — one curved side and a flat other. The collection of Trypillia metal of the National Museum of History of Ukraine contains five Szбkalhбt-type products from the excavations of V. Khvoyka. Due to the attribution, it was established that they originated from the settlements of Trypillia and Veremya (the last quarter of 5th millennium BC), Khalepya and Chernyakhiv (first half of 4st millen

Abstract:

The article considers the design of a vibrating working body of a subsoiler, developed for a method of tillage that improves energy and agrotechnical performance. Deep loosening of the soil allows to improve the quality of tillage. Based on the results of the analysis of the working bodies of the tools and methods for reducing the traction resistance of deep diggers (according to the type of working body, the layout of the working bodies on the frame of the tool, the use of vibration of the working bodies), a design solution is proposed that will significantly reduce the traction resistance of

Abstract:

The article concerns developing and implementing the technological principles for manufacturing the working bodies of chisel tools by casting grey cast iron with partial chilling of its working edges and surfaces interacting with the soil layer. High wear resistance of the working body is achieved by chilling its working part by means of a chill inserted into the mold, or by absence of coating in the corresponding zone of the mold. Severe overcooling of liquid cast iron contacting the chill or the metal surface of the mold causes crystallization of the meta-stable eutectics, and in the chilled

Abstract:

The machining operation should be targeted at dry or near dry machines to avoid environmental problems associated with the use of cutting fluids. To overcome the above situation, 80% of all machining operations are carried out with superior cutting tools such as CBN and ceramics. However, the price for the lathe chisel is still quite expensive. Cheaper carbide cutting tools are seen as a possible replacement for CBN and Ceramic insert cutting tools and are mostly processed by chemical vapor deposition (CVD) and physical vapor deposition (PVD) techniques. Therefore, a study was conducted on the

Abstract:

The conventional method of ridge expansion uses a mucoperiosteal flap elevation to allow bone corticotomy, which is followed by bone expansion performed with chisels and bone expanders. To facilitate corticotomy and avoid flap elevation, bone expansion can be performed in 2 stages. This case report presents a modified 2-stage bone expansion technique to achieve better implant stabilization and wound closure. This modified approach may be an efficient procedure for minimizing complications.

Abstract:

In conditions of increasing production and turnover of agricultural crops, soil degradation associated with wind and water erosion leads to depletion of fertile land and reduction of crop yields. One of the ways to increase the protective capacity of cultivated areas is deep loosening. The development of methods for assessing the efficiency and forecasting the use of tillage elements, taking into account economic, qualitative and agrotechnical requirements is an urgent task. To provide for the rational choice of a tillage element, the authors compared commercially produced domestic and foreign
