Abstract In mechanical design and manufacture, the minimum size of raw material of each part should be measured before processing. Generally, this size could be equal to the size of minimum bounding box. When the assembled parts of a product reach an enormous quantity, the measurement would be a rough work. This paper introduced an automated solving algorithm for the oriented bounding box based on principal axis of inertia, combined with CATIA structural tree recursive traversal algorithm according to CAA V5 Automation API, to implement an automated solution of the engineering acceptable minimum oriented bounding box of CATIA model.

Community Partnership Program in small home industry of making fish floss brand "Savitri" and "Tiaras" inKupang city in the form of application of electric centrifugation filter model has been implemented. One of the problemsin the production of Savitri and Tiaras fish floss is that there is still a lot of oil in the frying product which is only drainedon a simple sieve and then placed for some time on traditional tools of filter and paper that can cause low quality and lowquality, so it is necessary to reduce the oil yield frying fish floss product. In order to increase the added value and sellingvalue of the products, it is necessary synergy between Universities and Partners in the form of application of the results ofscience and technology to the public. The main components of the composer of the versatile filter are the cylindrical plateas the bucket of the filter, the cylinder filter, the electric dynamo as the centrifuge system rotator and the load-bearingconstruction. The method of this program is the provision of materials, design and manufacture of tools, demonstrationtools and the provision of a versatile filter cylinder system centrifuge model by the team, simulation tools, specialcounseling at the location of partners and suggestions as a follow-up in the endurance of production. The output of thisprogram can provide added value in the form of the use of this tool can improve labor efficiency, increase productivitypartners by producing 40 kg to 50 kg raw material, raw fish marlin, fish meat after cleaning, processed, fried, in andpacked into 80-100 packs of fish floss with the price of Rp. 40,000.00 per package weighing 250 grams. With estimatedpartners will earn a profit of Rp 3,200,000 - 4,000,000.00 per production or 12,800,000.00 - 16,000,000.00 per month incash and consumptions, as well as the abundance of non-greasy, clean and hybrid fish products

Practical Teaching

With the development of the times, undergraduate colleges and universities begin to transform and develop to adapt to the changing society, and put forward new requirements for practical teaching strategies, especially for applied undergraduate colleges. The reform of practical teaching is particularly important. Under the development of education transformation, the reform of mechanical design and manufacture and the practice teaching of automation specialty also occupy a very important position. Through the understanding of the reform of the practical teaching of this specialty, the effect of the reform is observed, and a reasonable teaching scheme is put forward to promote the steps of the transformation of the practical teaching.

Since 2007, we have offered single collimators for mini beams of sizes 5, 10 and 20 µm as well as a 300 µm scatter-guard to accommodate the fully focused beam. The advantages of varying the beam size were obvious, better signal/background ratio and the capability to raster with a coarse, larger beam, then fine tune with one of the mini-beam options. The mini beams proved to be a technical and popular success; however, the switching of the single collimators often involved staff intervention. The single mini-beam collimators were the precursors to the development of a triple collimator. This implementation incorporated two mini-beam collimators and a 300 µm scatter-guard on one post. The design was improved by consolidation of fabrication from a single piece of molybdenum block. It significantly improved the robustness, ease of initial alignment, reduction of background and increased automation. However, experimenters were still left with a choice of either a (5, 10 and 300 µm)- or a (10, 20 and 300 µm)-triple collimator. Recently, a quad collimator was developed and fabricated to provide a selection of mini beams of 5, 10 and 20 µm and a 300 µm scatter-guard, on a single post. We will present the mechanical design of multi-collimators, results of measured beam flux through the collimator pinholes.

Collaborative design is a new method for mechanical design and manufacture, how to improve the ability of design is the point problem. Data translation is a key problem for collaborative e design. In the paper, the problem of data translation is solved. Different design software for designer can complete the same task, which is based on the data transition and translation. The XML style of data is established, which is applied to express the relationship of data. The XML to STEP style is presented for system. Data can be transmitted among different software. The integration of system is established. At last, a prototype system is presented to demonstrate the methodology.

The Impact

This paper discusses the results of physic-chemical studies and the impact of the size of the dispersed particles in the manifestation of some metals in the ore minerals. With this purpose the samples of ore minerals from deposits Sary-Jaz ore area of Berkutskaya group were subjected to crushing to the minimum size in cus-tomized crushing installation. At this by the results of spectral analysis was determined the increase of quantitative metal content in the composition of the finest crushed sample compared to coarse crushing of raw material, especially an increase in the amount of silver in the 10-fold amount is observed.
