Design & Dev. of Drilling SPM Subsystem for Its Feed optimization

Book is about multi orientation of drilling .The multi spindle drilling Head are in different orientation .The Special Purpose Machine are machine that are useful to specific component .Number of machining processes can done on single machine which is made for only that component. Productivity depends upon many factors, one of the major factors being manufacturing efficiency with which the operation/activities are carried out in the organization. Productivity can be improved by reducing the total machining time, combining the operations etc. In case of mass production where variety of jobs is less and the quantity to be produced is huge, it is very essential to produce the job at a faster rate. This is not possible if we carry out the production by using general purpose machines. The best way to improve the production rate (productivity) along quality is by use of special purpose machine. A multi-purpose spindle for multi-tasking machine tools has been developed such that it can provide high power and torque for lower speed ranges while it rotates at high speeds for light duty machining. Multi-spindle head machines are used in mechanical industry in order to increase the production.
