A Value Added Approach to Milling Techniques - An analytical,scientific and practical approach to milling cutter selection and use A. INFORMATION PHASE - Become in expert on the milling operation through intelligent gathering ofall the facts and data 1 . Determine the specific operating conditions as clearly and sharply as possible. What? How? Where? When? Why? - It, actually occurs on the job! ASK questions - Machine Operator - Set-up Man - Foreman - 1st and 2nd Shift. 2. Study Part and Tool Print specifications for tool geometry and part changes. Analyze preceding and following questions. 3. Check Speeds and Feeds. 4. Check Location System, clamping system and gauging and coolants used. 5. Study the sequence of operations. 6. Observe operator on the job - Study the chips and check for human error! B. ANALYTICAL PHASE - Evaluate all the information and facts and suggestions gathered. 1. Previous ideas tried and similar jobs. 2. Suggestions from operator, set-up man, foreman. 3. All the information gathered. C. PROGRAM PLANNING STAGE - 1 . Outline definite plans to select the optimum cutting conditions. 2. Inform all personnel involved what part they will play in the plan, - Master Mechanic Dept., Process Engineer; Standards Dept., Purchasing, Machine Repair, Foremen, Set-up Men, and Men on the machine - All must know what is expected. 3. Coordinate efforts of all involved. D. PROGRAM EXECUTION PHASE - Carry out the planned program. E. SUMMARY AND CONCLUSION PHASE - 1. Have responsible, accurate reporting of results. Many milling applications are costly because they are not planned properly and checked accurately. 2. Adjust or correct the application to perfection. 3. Present the information on all changes made to those responsible for each phase of the job. OTHER VALUE ANALYSIS TECHNIQUES 1. Remove roadblocks - don't be stopped by shadows. If a roadblock occurs define it clearly and plan to overcome it. 2. Bring new information into each functional area - Utilize specialists to aid in problem solving. 3. Know the shop costs. 4. Evaluate each function. a. What is the item? b. What does it, cost'? c. What does it do? d. What else will do the job? What would it cost? 5. Utilize the best sources for information - get new ideas. 6. Use better human relations -- Permit everyone (from the man on the machine up to the top) to believe fie is contributing to a better way to do the job. 7. Put a dollar sign on every tolerance and finish. 8. Work on specifies - Not Generalities. 9. Use standard cutters wherever possible - They save money, time and minimize delivery problems. Once the "Value Analysis Approach" has been undertaken by the tool specialists, all phases of metal cutting principles and data become of vital importance. The metal removal process is affected by numerous variables. The technical material presented in this series of articles provides the basic principles of metal cutting, selection of cutting materials and application recommendations. By utilizing the information in the charts and tables, the tool engineer may determine changes in speeds, feeds, cutter material or set-up after evaluating his application. A course of action may be taken to provide maximum economy in the specific application.
