In the design of part of assembly technology clamp, the first is the determination of location programme,choosing location reference reasonably and analysising error in accordance with the characteristics of every process. if the location reference does not coincide with design reference , we must work out the dimension chain;the followed is the calculation of the cutting force by the characteristics of the processing .considering all the factors ,we will design the clamping programmes reasonably and calculate the clamping force, and design the clamp finally.
