Record notes
This case describes an application under the listed workpiece, tool and machining conditions. It does not guarantee tool life, cost or quality in other applications.
The source tool-life chart does not state a unit. The recorded values are shown without converting them into parts, time or output per edge.
Cost optimization is an application objective. The records do not include complete insert-price, machine-time and cost-per-part calculations, so no specific cost reduction is claimed.
Results apply to the workpiece and conditions recorded here. Tool life, surface quality and cycle time require validation for the actual material, machine, setup and parameters.
