【正文】 trip, 400inch clamping force. The characteristics of modern production are being smaller and smaller quantities and product specifications biggest changes. Therefore, in the final stages of production, assembly of production, quantity and product design changes appear to be particularly vulnerable. This situation is forcing many panies to make greater efforts to rationalize the extensive reform and the previously mentioned case of assembly automation. Despite flexible fixture behind the rapid development of flexible transport and handling devices, such as backward in the development of industrial robots, it is still expected to increase the flexibility fixture. In fact the important fixture devices the production of the devices to strengthen investment on the fixture so that more flexibility in economic support holders. According to their flexibility and fixture can be divided into: special fixture, the fixture binations, the standard fixture, high flexible fixture. Flexible fixture on different parts of their high adaptability and the few lowcost replacement for the characteristic. Forms can transform the structure of the flexible fixture can be installed with the change of structure ponents (such as needle cheek plate, Multichip ponents and flake cheek plate), a nonstandard work piece gripper or clamping elements (for example: mencement standard with a clamping fixture and mobile ponents fixture supporting documents), or with ceramic or hardening of the intermediary substances (such as: Mobile particle bed fixture and heat fixture tight fixture). To production, the parts were secured fixture, the need to generate clamping func tion, its fixture with a few unrelated to the sexual submissive steps: According to the processing was part of that foundation and working characteristics to determine the work piece fixture in the required position, then need to select some stability flat bination, These constitute a stable plane was fixed in the work piece fixture set position on the clampprofile structure, all balanced and torque, it has also ensured that the work features close to the work piece. Finally, it must be calculated and adjusted, assembly or disassembly be standard fixture ponents required for the position, so that the work piece firmly by clamping fixture in China. In accordance with this procedure, the outline fixture structure and equipped with the planning and recording process can be automated control. Structural modeling task is to produce some stable flat bination, thus, these planes of the work pieces clamping force and will fixture stability. According to usual practice, this task can be humanmachine dialogue that is almost pletely automated way to pletion. A manmachine dialogue that is automated fixture structure modeling to determine the merits can be conducted in an anized and planning fixture design reduce the amount of the design, shortening the study period and better distribution of work conditions. In short, can be successfully achieved significantly improve fixture efficiency and effectiveness. Fully prepared to structure programs and the number of material circumstances, the pletion of the first successful assembly can save up to 60% of the time. Therefore fixture process modeling agencies is the purposes of the program have appropriate documents. 加工基礎(chǔ) 作為產(chǎn)生形狀的一種加工方法，機(jī)械加工是所有制造過(guò)程中最普遍使用的而且是最重要的方法。 Depth of peration of a cutting tool to inches dollars is the tool to the work piece distance. Rotary cutting it to the chip or equal to the width of the linear cutting chip thickness. Rough than finishing, deeper peration of a cutting tool depth. Wears of Cutting Tool We already have been processed and the rattle of the countless cracks edge tool, we learn that tool wear are basically three forms: flank wear, the former flan
