| dc.description.abstract | Automobile industry for technology and capital intensive industry, the industry chain is quite large, affects related industry is very wide, a car is made up of about thirty thousand parts, steel, plastic, rubber, glass, mechanical, electrical, electronic, services and other industries, and professional talents including r&d, manufacturing, purchasing, marketing, management, maintenance and other skills, and assemble a complete car industry, so the car industry is called ＂the locomotive industry＂.
Manufacturing has always challenged the limits of cost, efficiency and quality, which is one reason the CMM′s position is so entrenched. The CMM is currently the most accurate tool available, even as sensing technology enters the measuring equipment arena. Vendors are constantly innovating, creating many variants from the basic mobile bridging CMM to meet a wide variety of needs and assist customers in reducing costs. Despite the prevalence of automation, highly accurate machines for measuring large parts are still indispensable, so there is still room for bulky, manually operated CMM with triggering detection heads. Even simple manual CMM is still common, and small studios that measure a small number of parts at a time are particularly interested in this measurement device.
In this study, in order to enter the automotive market, D company, hindered by the requirements of customers and the insufficient capacity of measurement equipment, compared the advantages and disadvantages of measurement equipment through measurement system analysis (MSA), and further measured by investment evaluation decision to achieve the optimal choice. | en_US |
