# 5-Axis CNC Mill Operator

*/JobTypes/5-Axis_CNC_Mill_Operator*

Departments: CNC Milling Department, Advanced Manufacturing, Tool and Die Room, Rapid Prototyping Shop, Precision Machining Cell.

## Job Type Profile

**Produces**: Delivers finished high-tolerance metal or plastic components that meet exact geometric dimensioning and tolerancing specifications. Generates first-article inspection reports and logs detailing tool life cycles and machine cycle times.
**Ai Surface**: Toolpath simulation, telemetry logging, and offset calculation exist entirely within digital control interfaces and memory. The physical loading of stock, auditory monitoring of tool chatter, and tactile inspection of surface finish require direct physical interaction.
**Core Tools**:
- [Fanuc CNC Control](/JobTypes/5-Axis_CNC_Mill_Operator/Products/Fanuc_CNC_Control)
- [CGTech VERICUT](/JobTypes/5-Axis_CNC_Mill_Operator/Products/CGTech_VERICUT)
- [Mastercam](/JobTypes/5-Axis_CNC_Mill_Operator/Products/Mastercam)
- [Epicor Advanced MES](/JobTypes/5-Axis_CNC_Mill_Operator/Products/Epicor_Advanced_MES)
**Responsibilities**:
- Load raw material billets into multi-axis workholding fixtures and establish part zero coordinates
- Execute and monitor complex G-code machining programs via the control pendant
- Measure cutting tool wear and input tool length and diameter offsets into the machine controller
- Monitor spindle load, coolant pressure, and chip evacuation to prevent tool breakage
- Conduct first-article and in-process inspections using micrometers, bore gauges, and coordinate measuring machines
