Modern CNC operated machines are extremely accurate in their own internal production process. Coupling that accuracy with the power of Statistical Process Control (SPC) creates a traceable measurement performance tracked to individual serial numbered products. Building the checking process into the CAM program automates the Quality Check and the SPC Control. Any Machine operating to SPC Control Limits creates dimension output always In Control, and much closer to the Nominal Dimension. Conformity to Tolerance is assured. Machines operating to on board SPC indicate cutting tool condition. The system is so powerful and accurate, Computer Coordinate Measurement Machines (CMM) become superfluous. Defects are not created as they are avoided. Product lot size is irrelevant as single piece control is achieved.
Implementation of such a system requires an Organization commitment. A Team of Product Engineering, Manufacturing Engineering, CNC Programming, Tooling, Machine Operators, Production Loading and Scheduling are needed to create the internal systems to bring SPC IN FLOW alive in a company.
SPC IN FLOW eliminates Manual and CMM processes for Product Conformity except as contractually or regulatory required. It is an Automation of the Dimensional Check and the tracking of Machine performance eliminates errors. The Labor savings is over 50% and the Product Quality is at a new level, very close to nominal dimensions and no defects.
The Highest Quality is always the cheapest Quality.
