• Educational article: (AP302) Productive Process Pattern: Dynamic re-machining [en]

  Productive Process Pattern™ from the in-process control layer of the Productive Process Pyramid™. The CNC machining process uses semi-finishing cuts or test cuts (slave features) that are representative of the subsequent finishing cut. The probing system on the machine is used to measure the cut feature and adjust the process through tool offsets to improve final part accuracy (using pattern AP301, Cutter parameter update).

• Educational article: (AP303) Productive Process Pattern: Thermal correction - machine drift [en]

  Productive Process Pattern™ from the in-process control layer of the Productive Process Pyramid™. Use a workpiece inspection probe to locate and measure the position of a critical reference feature in order to detect machine drift, or use an on-machine tool setter to track movement in a machine’s Z-axis caused by thermal effects.

• Educational article: (AP304) Productive Process Pattern: Tool condition monitoring [en]

  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: (AP305) Productive Process Pattern: In-process datum setting [en]

  Productive Process Pattern™ from the in-process control layer of the Productive Process Pyramid™. Use a workpiece inspection probe to measure datum features then store feature or part locations in the CNC in order to reset a current work coordinate system (WCS), or define a new WCS automatically. This procedure can be carried out whenever it is required during a machining process.

• Educational article: (AP306) Productive Process Pattern: Thermal correction - workpiece expansion [en]

  Productive Process Pattern™ from the in-process control layer of the Productive Process Pyramid™. Use a spindle probe to measure the size of a reference feature in the machine environment and compare it with the known size of that feature at 20 °C. Produce and apply a scaling factor or offsets to subsequent part measurements and proceed with machining operations based on parameters corrected for thermal effects.
