AB  - Teaching Assembly Planning Using AND/OR Graph
in a Design and Manufacture Lab Course
A product is a set of components linked together through joints during the assembly process
and each joint is made using an assembly technique. Assembly planning is the preparation of
the detailed instructions for the assembly of a product and involves (a) evaluation of the
processes and operations to be employed (b) selection of tooling and fixtures and (c)
determining the sequence of operations. Assembly planning is a well-established topic in big
industries like the aircraft and ship-building industries and there are specialist software
packages for these industries [1, 2]. Assembly planning can be done at several levels such as
the level of the entire production line, workstation level in a production line and at the product
level. This paper describes how assembly planning principles and their implementation at the
product level is taught to senior mechanical engineering students through the Design and
Manufacture Lab course, so that they can use assembly planning in their graduation projects.
The students were given a lecture on how multiple feasible assembly sequences can be
generated and the engineer can choose the sequence which he wants, based on criteria such as
machine availability, holding cost, tooling and fixturing needs etc. The AND/OR graph method
was used to explain how the multiple sequences for the assembly of a product can be developed
and presented for simultaneous consideration. They were explained how to develop an
AND/OR graph for the disassembly of a product which could be used to explain the underlying
(inverse) assembly process. The students were formed into groups of four and asked to
dismantle and assemble a bearing puller which had twenty-nine constituent parts, and then to
establish the AND/OR graph for the disassembly. The students were made to realize the
benefits of handling sub-assemblies separately. They were then asked to extract the possible
assembly sequences and choose one for the manufacture of a hypothetical 1000 units per week.
They were prompted to identify suitable fixtures for the process they chose. A questionnaire
survey was carried out at the end of the assignment. The paper will describe the method, the
tasks in the assignment, student performance, answers to the survey questions and the lessons
learned.
