# Introduction

## Task

The “Kinematic Optimisation” cycle (KinOpt) allows an increase in machining accuracy on 5-axis machine tools.

Geometric inaccuracies in machine kinematics are determined by a measurement run. This is followed by a calculation program to define optimised kinematic parameters which can then be entered in the machine configuration.

## Effectiveness

The kinematic parameters are improved compared to the drawing dimensions and this leads to an enhanced precision of the workpiece.

## Condition

The following is required for the measurement run:

- an absolutely accurate XYZ probe or
- a calibration sphere or
- alternative measuring equipment

## Notice

Cycles are additional options and subject to the purchase of a license.

## Release Note

This additional option is available as of CNC Build V3.1.3068.09..

## Restrictions

The method is restricted to the following kinematics:

- KIN_TYP_9: Cartesian CA head
- KIN_TYP_57: BC table
- KIN_TYP_58: AC table
- KIN_TYP_59: Cardanic CA head
- KIN_TYP_60: Cardanic CB head
- KIN_TYP_80: AB table
- KIN_TYP_90: Cartesian AB and CA head, cardanic CA head

## Notice

Other kinematics

A number of other kinematics are special cases of the above listed kinematics. For example, the Cartesian CA head only supports the KIN_TYP_9. However, machines which were previously operated as KIN_TYP_10, KIN_TYP_25 or KIN_TYP_28 can also be parameterised as KIN_TYP_9.
