The characteristics of sheet metal process are little loss of material during process, the short processing time and the excellent price and strength. It has been widely used in autobody, electronic components, aircraftbody, etc. Lancing is a press operation in which a single-line cut or slit is made on part way across the strip stock, without removing any metal. In this paper, we examined the validity of finite element method analysis on the automobile CTR-PLR -L/R stamping process by using the lancing engineering method. As a result, it has shown that the proper lancing engineering method could prevent fracturing by improving sheet metal flow.

This paper introduced the affordable housing support programs and system of the State of Michigan and Lansing Metropolitan Area and reviewed the affordable housing plan of Lansing area. This paper also examined their challenges and efforts to solve the affordable housing issues with additional analysis. The affordable housing planning process was also presented with a comprehensive analysis and future prediction of demographic characteristics and housing supply and demand for affordable housing. Especially, the trend and future forecast of the elderly and low-income households who have a significant impact on the affordable housing demand are considered. The U.S. and South Korea have different housing characteristics and situations. A part of the plan and suggestions of Lansing are somewhat unfamiliar, and it is difficult to introduce their suggestions into our policies. However, the affordable housing plan of Lansing Metropolitan Area suggested various solutions to solve the issues, and some of them deserve to be considered on our housing policy making.

Sheet metal forming is one of the most useful and important method in manufacturing of the autobody panels because of the excellent production rate. The objectives of sheet metal forming processes are getting a desired geometrical shape of products with good quality, low cost and reasonable lead time. In this paper, we examined the validity of finite element method analysis on the automobile FRT-PLR-L/R stamping process by using the lancing engineering method. Lancing is a press operation in which a single-line cut or slit is made on part way across the strip stock, without removing any metal. As a result, it has shown that the proper lancing engineering method could prevent fracturing by improving sheet metal flow.
