As there are various machine configuration and frequent changes of cutter orientation in 5-axis machining, the standard NC codes are not inter-exchangeable among machines. This phenomenon induces a lot of cutting difficulties and machining problems such as the inconvenient working process for operators and very low cutting efficiency. At present, some advanced machine controllers already can accept the APT code besides NC code to increase the cutting flexibility. They also offer some advanced machining functions such as tool center point control and spatial compensations of tool, etc. By way of APT interpreting, the common controller can also implement these advanced functions. Besides, CAD/CAM software also supports APT post-processor to generate NC code for different machine configurations. This means the application of ATP program has played an important role in five-axis machining. However, although CAD/CAM software supports the interpretation of APT program as a core key technology of five-axis machining, the manufacturers of controller with advanced functions are unwilling to open their system. Up to now, there has been few related research papers published on this topic. In this paper, we proposed an APT interpretation method for five-axis machining. This method includes seven functional modules and related implementing procedures. A case study has been adopted to demonstrate the feasibility of the proposed method. The research result could be adopted as a reference to develop the value-added technology in 5-axis machine tool application for academy and industry.

‘Management’ at the business capitalism covers the vehicle of some aspects including the employee, course, service, network, and any kind of stuffs related to this case. In line with the system of business management, every single company might be in uniformity according to the common standard of capitalism despite having differences in the vision and mission. In this case, Waroeng Steak (WS) Restaurant in Demangan, Yogyakarta intentionally applied Islamic spiritual management. WS uses several kinds of teachings and trainings according to Islamic Sharia in the daily process. This concept concerns to the employees’ behavior upgrading and company progression through WS’ timeline program including daily, weekly, and annually activity striving for a great spiritual and economic orientation in the future. This paper argue despite the spiritual training for employees of WS might not be considered practical by capitalist standard, it is effective in bringing both spiritual and economic benefits to both company and all members of the staff. The research result that capitalism meet religion in terms of the production could lead to another standpoint at the collaborative intention in gaining positive benefit in successful business operation. Religion in regard to spiritual management in business has a significant role in bringing both individual upgrading in the class of devotion to God and the reflection to the good ethic in undergoing the working process, it is finally so-called a spiritual company that will be distinctively differ from the other existential companies. Keyword: spiritual management, employees’ habit, company characteristic upgrading

The working posture of an individual influences his working efficiency and working efficiency significantly affects productivity. An index of productivity as a function of posture-related variables is needed to assess the significance of posture's effect on productivity. A posture-productivity index expresses the capability to increase productivity by changing working posture. The index is based upon the following nine ergonomie guidelines or contributing factors for working posture described by Ayoub (1971): static work, overload of muscular system, mechanical advantage, joint positions, unnatural postures, proper sitting posture, allowable change of posture, accommodation of large operators, and operator training. The advantage of this procedure is not only to be able to determine the posture-productivity index, but more importantly, the capability to improve worker efficiency by modifying working posture is indicated. Such an indication will be an invaluable tool, especially since most changes to improve working posture would normally require minimal investment.

Solving the problem of the dissolution of mineral substances (in particular, lime) in biological fertilizers (bioreactor waste after production of biogas and biodiesel) and the use of these fertilizers in agriculture can increase the productivity of the main crops (wheat, rye, corn, oats, potato) in 2–3 times and therefore is an urgent task. The complete dissolution of lime in biological waste in a ratio of 1 to 3 in a closed container without the use of mixing or other means of intensification of the process, requires a significant expenses of time (about 3 weeks or 500 hours), does not satisfy agricultural enterprises. Under of using of heating of a mixture of lime with waste for intensification the dissolution, a lot of useful microorganisms die in it, which reduces the value of biological fertilizers based on it. Known equipment for mechanical dissolution: screw and drum mixers, vibration mixers, centrifuges - work with relatively small amounts of waste (up to 1 ton) and therefore do not provide the necessary productivity of the working process, while increasing the mass of the portion leads to a noticeable decrease in the dissolution efficiency. In the work, a scheme of a special installation for dissolving mineral substances in biological fertilizers is developed, which will provide a combined static and dynamic load of a portion of fertilizers with its additional heating, which will increase productivity and reduce the energy intensity of the work process. The equations of motion of the executive element and the dependencies to determine the main operating parameters of the installation are obtained. On the basis of their a mathematical model and design calculation method can be developed.

Modern surface mine safety and productivity data were summarized as part of the Bureau of Mines Industrial Hazards/Human Factors program. Safety Information was obtained through mine site visits (observations and interviews), national actuarial statistics, tables, and MSHA accident reports. The examination of 148 accidents showed three specific contributing factors. First, mining is a rugged industry in which the environment is unstable and unpredictable. This unpredictability contributes to both accident incidence and severity. Second, large vehicles (120 ton haulpacks) move, fully loaded among small vehicles and people. This mismatch in size makes a collision a very severe accident. Finally, job design was found to be a contributing factor in accidents. Sixty-seven percent of the sampled accidents involved the misuse of a tool or procedure. These are not random errors, but reflect short cuts the workers take to save energy and increase productivity. It was proposed that correct job procedures would not be followed if the more efficient shortcuts were available. Consequently, the next step in this program is to develop modified job procedures for a few selected tasks. These procedures would be redesigned to improve efficiency and avoid the safety hazards found in the workers' make shift shortcuts. This approach changes the focus from emphasizing safety to emphasizing productivity through the design of safe and efficient job procedures.
