Types of Tap
Types of Tap HAND TAPS ISO 529 These are straight flute general purpose tools which can be used for both machine or hand tapping. They are generally the most economical tool for use on production runs, but are best on materials that produce chips, or where the swarf breaks readily. Where deep holes are to be tapped, in materials which produce stringy swarf, serial taps may be needed, especially for coarse threads. ISO 529 hand taps can be supplied in sets of three; bottom, second and taper leads, or individually. BOTTOM TAPS have a chamfer (lead) of 1–2 threads, the angle of the lead being around 18 degrees per side. They are used to produce threads close to the bottom of blind holes. SECOND TAPS have a lead of 3-5 threads at 8 degrees per side. They are the most popular and can be used for through holes, or blind holes where the thread does not need to go right to the bottom. TAPER TAPS have a lead of 7-10 threads at 5 degrees per side. The taper lead distributes the cutting force over a large area, and the taper shape helps the thread to start. They can therefore be used to start a thread prior to use of second or bottom leads, or for through holes. IMPORTANT NOTE ON TERMINOLOGY! In the U.K. bottom taps are often referred to as ‘plugs’. In North America second taps are often referred to as ‘plugs’! This can easily lead to confusion. To avoid problems when ordering it is best to use the terms bottom, second and taper. -

Utilization of Waste by Preparing the Product from Swarf Forging of Alloy
et International Journal on Emerging Technologies 6(2): 181-183(2015) ISSN No. (Print) : 0975-8364 ISSN No. (Online) : 2249-3255 Utilization of Waste by Preparing the Product from Swarf Forging of Alloy Steel (16MNCR5) Abid Nazir and Harvinder Lal Department of Mechanical Engineering, RIET, Phagwara, (PB), India (Corresponding author: Abid Nazir) (Received 01 October, 2015 Accepted 06 November 2015) (Published by Research Trend, Website: www.researchtrend.net) ABSTRACT: The aim of thesis is to prepare the product from swarf forging of alloy steel (16MnCr5). This thesis is an example of how the waste fraction can be transferred from waste to a resource that can be used in other industrial processes. It offers both environmental and economic benefits. Swarf forging gives better control, environmental credits, cost savings an increased margins. Swarf collected from lathe, milling, drill or any other cutting machine is cleaned by degreasing, pickling and acid pickling. Preliminary heat treatment is done to eliminate the work hardening, moisture content and impurity content. Swarf can be continuous, discontinuous or powder form. After collection of swarf, put in mild steel tube for compression. Compression of swarf is done by hydraulic press. The force is applied on piston which is inserted in tube. After compression, swarf which is in form of cylinder is taken out. After this heat the samples are heated and forged with the help of manual hammers or with help of hydraulic hammer. After forging hardness, density and microstructure are checked. The values indicate that product made by swarf forging can be used for low load application like door handles, hangers etc. -

Reflecting recent changes in the polymer industry, the sustainability of biobased polymers allows them to be used for general and engineering applications. This expansion is driven by the remarkable progress in the processes for refining biomass feedstocks to produce biobased building blocks that allow biobased polymers to have more versatile and adaptable polymer chemical structures and to achieve target properties and functionalities. In this review, biobased polymers are categorized as those that are: (1) upgrades from biodegradable polylactides (PLA), polyhydroxyalkanoates (PHAs), and others; (2) analogous to petroleum-derived polymers such as bio-poly(ethylene terephthalate) (bio-PET); and (3) new biobased polymers such as poly(ethylene 2,5-furandicarboxylate) -

Some relative cutting characteristics of the metal are understood. speeds using HSS tools are given in Table 2. Cutting speeds are also dependant on the tool material. Cutting power and machinabilty Higher speeds can be enjoyed with the use of carbide or poly-crystalline diamond (PCD) tooling. The mean specific cutting force (ks1.1) of magnesium is 280 N/mm2, this is much lower than that of In general, cutting speeds are between aluminium (approx 640 N/mm2). The result of this 200 – 1800 m/min with feed rates greater than means that there is a reduced load on the cutter and 0.25 mm/rev for turning and boring operations. -
Environmental Biodegradability of Recombinant Structural Protein
www.nature.com/scientificreports OPEN Environmental biodegradability of recombinant structural protein Yuya Tachibana1,2*, Sunita Darbe3, Senri Hayashi1, Alina Kudasheva3, Haruna Misawa1, Yuka Shibata1 & Ken‑ichi Kasuya1,2* Next generation polymers needs to be produced from renewable sources and to be converted into inorganic compounds in the natural environment at the end of life. Recombinant structural protein is a promising alternative to conventional engineering plastics due to its good thermal and mechanical properties, its production from biomass, and its potential for biodegradability. Herein, we measured the thermal and mechanical properties of the recombinant structural protein BP1 and evaluated its biodegradability. Because the thermal degradation occurs above 250 °C and the glass transition temperature is 185 °C, BP1 can be molded into sheets by a manual hot press at 150 °C and 83 MPa. The fexural strength and modulus of BP1 were 115 ± 6 MPa and 7.38 ± 0.03 GPa. These properties are superior to those of commercially available biodegradable polymers. The biodegradability of BP1 was carefully evaluated. BP1 was shown to be efciently hydrolyzed by some isolated bacterial strains in a dispersed state. Furthermore, it was readily hydrolyzed from the solid state by three isolated proteases. The mineralization was evaluated by the biochemical oxygen demand (BOD)‑ biodegradation testing with soil inocula. The BOD biodegradability of BP1 was 70.2 ± 6.0 after 33 days. Many commercially available polymers have some associated environmental problems1,2. Te increase in the production and subsequent disposal of synthetic polymers causes serious environmental pollution because these polymers do not degrade in the natural environment. -
