What you need to know about making sizing adjustments on a CNC machining center or turning center…

 

Making sizing adjustments is at the very heart of being able to run a CNC machine. Without the ability to make them, you will not be able to make good parts.

When a CNC setup person sets up a CNC machining center or turning center, they do their best to measure certain cutting-tool-related values and enter them into the CNC. These values vary based upon the machine and cutting tool type, but in general, they tell the CNC control where the tip of the cutting tool is relative to the workpiece being machined. In almost all cases, they will not be perfect – that is, they will not be precise enough to ensure that every workpiece attribute gets machined within its specifications. Sizing adjustments must be made while running the first workpiece to ensure that all workpiece attributes are machined at there intended sizes.

Assuming that more than one workpiece must be machined, cutting tools will wear as more and more workpieces are machined. Tool wear will cause machined surfaces to grow or shrink (in the direction of the cutting tool). The more workpieces that must be machined and the smaller the tolerances to be held, the more likely it is that sizing adjustments will be required during production runs to keep machined surfaces from growing or shrinking out of their tolerance bands.

This text will show you what it takes to get and keep CNCs running good parts. It is divided into five lessons:

1) What are sizing adjustments and why are they required?

  • Learn what sizing adjustments are, why they are required, and when you will be making them

2) A little math

  • Learn the arithmetic calculations that are required to make sizing adjustments

3) Taking measurements

  • Learn about the measuring devices (gauges) you will be using to take measurements on workpiece attributes

4) Tolerance interpretation

  • Learn how to evaluate whether measured values are acceptable, and if they are not, how to calculate the amount of deviation from the intended size

5) Making sizing adjustments on a CNC machine

  • Learn the techniques used to make sizing adjustments at the CNC machine

Each lesson includes a presentation, reading material, and a test that will be graded.  If you have questions during a lesson, answers are just an email away.

When you complete this class, you'll know what it takes to size in each tool during setup and adjust for tool wear during a production run. While you will still need hands-on practice (mostly with gauges), you will know what it takes get and keep a CNC machining center or turning center running good parts.
