PROCESS/TIME STUDIES

IN ORDER TO MOVE FORWARD WITH A PROJECT, IT IS NECESSARY TO DEVELOP THE PROCESS.

PROCESS DEVELOPMENT

Study the Part Prints
Identify Location Point Requirements
Consider the Part for Number of Operations Required
Ask......Will This Part Fit Best on a Lathe, VMC, or HMC or a Combination of Machines
Always Strive to Complete the Machining in One Operation if Possible
If the Machine is a VMC Should it Be an APC Type
If the Work Holding Will Be Complex Make Rough Layouts to Assure Capability
Establish the Number Of Parts Machined in One Clamping (Parts On)
Based on the Above, "Write" the Process and Establish the Cut Tooling Required for Each Step

TIME STUDY

With the Process Developed, and the Tools Selected, It is Possible to Create a Time Study. There is software Available for This. However, We Prefer Not to Use It. We Feel That There is No Substitute For Practical Experience and Software Can Not Make Intuitive Decisions.

Cutting Tool Manufacturers Do Provide Considerable Information Regarding Speeds and Feeds. You Will Find That a Large Range in the Values Are Given. Some People Use the Mean of These Values. We Prefer to Look at Each Case Individually and Tend to be More Conservative.

The Non-Cut Time (Rapids, ATC, APC, Accel/Decel...) Will Vary Greatly From Machine to Machine. We Use the Builder's Information Coupled With Experience and Testing For These Values.

HOW DO WE GET STARTED?

GOOD INFORMATION WILL ENABLE US TO MORE PRECISELY ADDRESS YOUR EXPECTATIONS. PLEASE CONSIDER THE FOLLOWING:

Part Prints - Can Part Prints Be Provided as Electronic Files? AutoCad, VersaCad, or SolidWorks is Preferred. PDF is Okay But Not Our First Choice. Faxed Copies of Reductions of Large Drawings Are Very Difficult to Read. If the Part Is a Casting or Forging, Please Provide This Drawing As Well.
Material Specification - If the Material Spec Refers to an Internal Document or Standard, Please Provide This Information.
Production Time Available - How Many Shifts Are Worked and What is the Efficiency Standard?
Is This Part Currently Being Produced? If So, Please Provide Any Pertinent Information Available
Is There a Production Rate (Cycle Time Per Part) Target?
Are There Any Internal Specs Regarding Tolerances or Finishes?
Are Sample Parts Available? Castings, Forgings, Machined Parts.....This is Very Helpful
