    When machining a component using a CNC machine tool, the quality of the finished part, for example surface finish and adherence to tolerance, is highly dependent on the positioning and contouring performance of the machine. To maintain machine performance, use a telescoping ballbar to conduct a rapid performance check as part of a preventative maintenance regime, before machine performance is compromised.

  • Educational article: (AP205) Productive Process Pattern: Tool identification Educational article: (AP205) Productive Process Pattern: Tool identification [en]

    Productive Process Pattern™ from the process setting layer of the Productive Process Pyramid™. An on-machine tool setting system is used to establish tool length and diameter offsets when replacing tools. As a safety check, the measured values are compared against reference dimensions with a tolerance applied: if the tool length or diameter deviation is greater than the allowed tolerance, the process will stop safely before any machining takes place or any damage can occur.

    Productive Process Pattern™ from the in-process control layer of the Productive Process Pyramid™. When tool breakage is identified as a significant expected risk, it is useful to monitor the condition of the cutting tools which are being used. Performing a tool breakage check immediately after using a tool can help to infer whether the component has been correctly machined - particularly for components where tool breakage is the primary cause of failure.

  • Educational article: (AP400) Productive Process Pattern: Process reporting Educational article: (AP400) Productive Process Pattern: Process reporting [en]

    Productive Process Pattern™ from the post-process monitoring layer of the Productive Process Pyramid™. Most CNC control systems have the capability to send customised information through RS232 serial ports, an Ethernet connection, or to the hard disc of the CNC control. The reporting capability allows a traceable record of the ‘route’ used to manufacture a component to be stored along with the component inspection data. For example, it is possible to log any detail of machine updates, required re-machining, or tools that were broken.
