Special purpose machine are widely used for special kind of operations, which are not economical on conventional machines. It is design for getting higher accuracy at desired condition. Face milling in industrial component is followed by a milling process. In the initial core bore is develop on the component with the help of required tool material. A Special Purpose Machine introduced here can be operated manually or automatically, as per the condition or a mechatronic based system can be developed that will work with different speed. A SPM can be developing with two separate units which perform milling & boring operation sequentially. SPM introduced here is automatically start operation by sensing work piece on table; it helps in start & end of cycle. Milling Machine performs first milling operation of face of 105 x 135mm size and then boring machine for ø41.30H7 × 20mm deep cylinder block. In this the job is machined on two machines and two fixtures are used and operation is performed, hence it takes 10 min. to completion of one job. In this method Bore to face perpendicularity not maintained, so accuracy is low. The production rate is very low due to time required for two times loading and unloading of job, operational accuracy required. The manpower is required is more & skilled. In order to successfully come up with these problems, company decided to develop Special Purpose Machine. It will save production time and increase the production rate.
