I have a large, broad machined face that I want to control. There is one portion of the surface that I am truly concerned with, and I plan to use Datum targets to hold flatness in a specific area. How can I control the flatness of the rest of the surface?
Ex: Datum target area flatness is .002 within a diameter of 16.00", but I want to state the rest of the surface needs to be within a flatness of .010

In this whitepaper, we'll provide insight into why and when it makes sense for U.S. manufacturers to reshore prototyping and production, and how companies can leverage the benefits of working with local design, prototype, and manufacturing partners during the pandemic and beyond.
This 22-page report from Instrumental identifies the most common production defect types discovered in 2020, showcases trends from 2019 to 2020, and provides insights on how to prevent potential downtime in 2021. Unlike other methods, Instrumental drives correlations between a variety of data sources to help engineers find and fix root causes. Download Now
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
