This research is to study the cutting tools product in reverse engineering for turning milling and drilling included Tool holder Arbor and Insert tool. It is sampled the imported cutting tools from three areas worldwide composed with Sweden United State of America and Japan. The study emphasis in Arbor 136 mm. (6 tooth) Arbor 63 mm. (4 tooth) the changeable Insert tool typeTool bolder 20 mm. and Tool holder for turning. The result is found that Tool holder materials has the mixture of 0.387-0.437 %C hardness is 39.36-53 HRC which was full hardening. The price of Arbor (6 tooth) surveyed from four brands maximum is 22350 Baht and 2.41 times of price differentiation. The price of Arbor (4 tooth) surveyed from two brands maximum is 19000 Baht and 0.1-0.5 times of price differentiation. The price of Tool holder surveyed from three brands maximum is 14300 Baht and 0.15-0.55 times of price differentiation. And the price of Tool Holder for turning surveyed from four brands maximum is 1900 Baht and 0.5-1 times of price differentiation. The provider set up Tool holder and Insert tools will not be compatible together for marketing strategy. There are not much key player providers so there is no strong competition. The provider forces to distribute a set of 10 Insert tools and the most of Tool holder is Hardening and quenching not less than 39 HRC. The metal removal might be necessary use high technology and precision CNC Milling Machine. Therefore the study will lead to design and produce the prototype of cutting tools complete set which is compatible with Insert tools in all processes for turning milling and drilling. This cutting tools complete set differentiates from others because it helps to reduce costs reduce times and work comfortable. The development of compatible cutting tools complete set is the approach to reduce costs and times of work decrease maintenance costs and it will be the foundation to development of multi-function cutting tools complete set in place of the imported cutting tools.

Alteration of Denim Clothes for Re – Use : A Case Study on Female Students at Rajamangala University of Technology Phra Nakhon Rajamangala University of Technology Phra Nakhon The objectives of this research were (1) to design and alter old denim clothes for re-use (2) to study the female students’ behavior on purchasing used clothes and (3) to evaluate their satisfaction towards the altered old denim clothes. The stratified sample were 353 female students at Rajamangala University of Technology Phra Nakhon. The research tools were a questionnaire and 6 styles of original products. The data were analyzed by using a standard statistical method and reported as percentage means and standard deviation. Designing and alteration of old denim clothes include decorative addition. The total of 6 styles having an equal number of altered old shirts skirts and trousers were used in the study. It was found that 66.90 percent of female students purchased approximately 1 - 2 pieces of used clothes once every in 4 - 6 months. The most popular products were casual clothes namely jeans of which the satisfactorily pretty styles mainly affected their purchase decision.

The adsorption of cotton fabric is improved by treatment with sodium hydroxide which is called causticization method. In the method it is necessary to wash off unreacted sodium hydroxide from the fabric and then neutralize with some acids such as acetic acid and sulphuric acid. In this research citric acid was used to neutralize causticized fabric and anticrease finish on cotton fabric. The citric acid is non-formaldehyde anticrease finishing agent. So that the two processes i.e. causticization and anticrease finish could be combined into one continuous process. And it was found that the causticization would improve some properties of anticrease fabric with citric acid. From the result it showed that the anticrease fabric had lower tensile strength than untreated fabric. The anticrease finish with 6% w/v citric acid had higher tensile strength than 8 and 10 % w/v respectively. When concentration of acid curing temperature and time were higher wrinkle recovery angle would be increased. The effect of catalyst showed that anticrease finish using sodium hypophosphite as catalyst was higher wrinkle recovery angle and tensile strength than non-catalyst finish. The causticization before anticrease finish would increase tensile strength and whiteness of fabric when compared to only anticrease finish. The effect of catalyst showed that at low acid concentration increasing of catalyst didn’t have effect on tensile strength and wrinkle recovery angle value. At higher acid concentration trend of tensile strength was decreased whereas wrinkle recovery angle increased and slightly effect on whiteness.
