- 1. J.B.INSTITUTEOFENGINEERINGANDTECHNOLOGY DEPARTMENT OF MECHANICAL ENGINEERING STUDY OF MANUFACTURINGPROCESS OF A MISSILE COMPONENT AT BDL Mini project on [carried out at : BHARAT DYNAMICS LIMITED BY SHAIK RESHMA 13671A0395 Under the guidance of DIWAKARA RAO
- 2. ABSTRACT Frame component, which is the component to be manufactured, consists of several important parts in the missile. In the present work an optimal production process is discussed which reduces the overall cost of manufacture and simultaneously maintaining the quality required. A study on the criticality of the component, the particulars of the machine and its accessories, the control systems, the programming features, development of part program, the inspection, results and the conclusions, are included in this project.
- 3. INTRODUCTION The required missile component is produced by performing CNC turning operation initially. It has to go through a sequence of operations to give an effective result.
- 4. SEQUENCE OF OPERATIONS facing turning parting Step turning tapering
- 5. FACING : In the context of turning work involves moving the cutting tool at right angles to the axis of rotation of the rotating work piece. This can be performed by the operation of the cross- slide, if one is fitted, as distinct from the longitudinal feed (turning).
- 6. PARTING : This process, also called parting off or cutoff, is used to create deep grooves which will remove a completed or part-complete component from its parent stock.
- 7. GROOVING : Grooving is like parting, except that grooves are cut to a specific depth instead of severing a completed/part-complete component from the stock. Grooving can be performed on internal and external surfaces, as well as on the face of the part.
- 8. BORING : Enlarging or smoothing an existing hole created by drilling, molding etc.i.e. the machining of internal cylindrical forms (a) by mounting work piece to the spindle via a chuck or faceplate b) by mounting work piece onto the cross slide and placing cutting tool into the chuck.
- 9. DRILLING : This is used to remove material from the inside of a work piece. This process utilizes standard drill bits held stationary in the tail stock or tool turret of the lathe. The process can be done by separately available drilling machines.
- 10. TOOLS AND INSERTS Tool Selection for cnc machining is an art as cnc machine can do vast variety of operations like turning facing threading taping profile or arc machining.
