This paper discusses the gear pump shell drilling fixture design and process design. The content of this design involves the analysis of the parts, determine the blank, the technological design and fixture design and 2D and 3D drawing of the graph. Understand the parts of process, design the structure of the blank, choose parts processing benchmark, design of parts processing route. To formulate the overall scheme of the fixture, such as understanding multiple positioning methods, carries on the contrast and analysis of selecting one of the most suitable for positioning scheme of machining parts. Select tool, Chad parameters such as cutting speed, feed and cutting depth, according to the machining process, calculate the spindle speed of each work step, 3D modeling, writing instruction.
