Process Capability

Process Capability is the final stage of the project and, when completed, marks the readiness of the machining cell to begin production.  With many years of experience with process capability, John Hart engineers will proactively lead the client through this critical process with a goal to complete the required process testing in a most efficient and timely manner.

During this stage, John Hart engineers will work proactively with both the clients’ engineering and quality personnel, and the cutting tool vendors’ support staff to consolidate each individual party into a team with a common directive.

The typical process capability consists of:

• Proving out of CNC programs
• Cycle time enhancement
• Dimensional targeting
• First part submission to quality engineers for 100% inspection (often known as ISIR)
• A small batch test run of parts as an initial indication of process capability (often known as a mini CpK)
• A final capability study (CpK) with a large run of parts under production conditions (clients’ machine operators, full machining rates etc.)
• Finals reports prepared detailing the capability of the process to begin production

Once all capability testing criteria have been met or exceeded, production can commence.

John Hart engineers will then complete training of the clients operator and maintenance staff and prepare the final documentation of the process for submission to the client.  This marks the completion of the project.
