Purchasing a CMM is not unlike any other capital investment for the business, it needs justification and an achievable "pay-back".

Its been heard many times that a CMM "does not produce chips", so its an overhead.
Its true; there are no "chips" but inspection certainly does make a significant contribution to the bottom line. Consider -

Has your business been "audited" by a potential customer and you didn't get the contracts?
How many contracts or orders are "lost" because your inspection is not as good as competitors?
What is the effect on your customers receiving poor quality parts?
How many customers want inspection report generated automatically?
Do you even know if you have lost customers because of your inspection failings?

NEW machine Justification worksheet
Prepare your answers to the questions posed in the form and calculate payback for the investment.
CMM Upgrades and retrofits from Hexagon Metrology can be applied to virtually all makes and models of CMMs. 
This form will also will help you decide if an upgrade or retrofit is appropriate.

Calculate the Payback

Payback on upgrading your present CMM can be broken down into the following categories:

  • Reduced inspection time and increased productivity
  • Reduced downtime
  • Reduced scrap and rework
  • Intangible benefits

You will need the following information to Calculate

REDUCED INSPECTION TIME

Hours to Inspect Part In Process =
Internal Labour Rate per Hour =
Parts per Month for inspection =

Hours to Generate Inspection Report =
Internal Labour Rate per Hour =
Parts per Month for inspection =

Hours to Final Inspection Part =
Internal Labour Rate per Hour =
Parts per Month for inspection =

REDUCED PRODUCTION TIME

Idle Hours due to down time =
Internal Labour Rate per Hour =
Parts per Month for inspection =

CNC Machine Idle Hours due to First Piece Inspection =
CNC Machine Cost per Hour =
Parts per Month for inspection =

REDUCED SCRAP & REWORK

Cost of Monthly scrap =
Cost of Monthly Rework =

RESULT
Payback in Months = Cost of CMM / Total Savings per month
