A revolution in 5-axis machining accuracy

5-Axis Auto Tuning System

5-Axis Auto Tuning System—An Overview

When machining with a 5-axis CNC machine tool, it is common for geometric errors to affect the quality of the part. Commissioning and general wear & tear can take a toll on the kinematic chain and result in potential quality issues in your finished parts. Machines come out of level over time and even the smallest bumps can cause geometric errors. To maintain high-level, 5-axis machining, an accurate on-site tuning must be done to compensate for any geometric errors.

The 5-Axis Auto Tuning Difference

  • The machine performs the tuning quickly and accurately
  • Compensates up to 11 geometric errors, including volumetric accuracy
  • Adjustments can be performed in approximately 10 minutes vs. 5 hours or more for manual methods
  • Does not require a high level of skill

Geometric 5-Axis Errors

There are 11 possible kinds of geomteric errors on 5-axis machines, including displacement of the center position of the rotary axis, tilt of the rotary axis with respect to the orthogonal axis, thermal deformation and changes over time in the installation environment. These errors can cause steps in slope machining, shape defects in curve machining and other problems.

Okuma´s Solution

Geometric errors change over time due to, for example, floor surface movement. Therefore fine tuning of geometric errors is needed on the shop floor machines for highly accurate 5-axis machining. Okuma‘s 5-Axis Auto Tuning System helps the operator to correct 5-axis geometric errors quickly and easily.

Okuma has developed the 5-Axis Auto Tuning System to manage and compensate geometric error changes and Thermo-Friendly Concept to stablise the thermal deformation changes. These both influence 5-axis precision machining. In other words Okuma has made 5-axis precision machining quick and easy with high accuries and at the same time helps to prolong your machine and product‘s lifetime.

Advantages

Only 4 error types can be detected manually while our 5-Axis Auto Tuning System is able to dectect 11 types of errors.*
