Pre-Process Engineer (Turning & Milling)

Job Definition

The Pre-Process Engineer will be responsible for taking existing CAD drawings and 3D models and generating, optimising, and validating CNC programs to enable these parts to be manufactured using both turning and 3,4 and 5 axis machining centres. This role involves using simulation software (including Fusion 360 and Alpha Cam) to define repeatable machining processes, setups, tooling strategies, and work-holding methods for both fully automated robot loaded cells and standard CNC machining centres. 

Responsibilities

• Create, optimise, and validate CNC programs for turning and milling centres. 

• Use simulation and first-off proofs to ensure safe, efficient, and repeatable machining processes. 

• Define setups, tooling strategies, and work-holding methods. 

• Optimise cycle times and improve machine utilisation. 

• Maintain program version control and documentation integrity. 

• Prepare complete machining job packs, including routings, inspection requirements, and tooling lists.  

• Coordinate with Planning to confirm realistic scheduling and flag potential risks before release.  

• Support FAIRs, PPAPs, and compliance with ISO 9001, AS9100, and customer standards. 

• Work closely with engineering, quality, and maintenance teams to improve manufacturing processes.

• Ensure all activities comply with health, safety, and quality standards.

  Essential Requirements

• Proven experience as a CNC Programmer within a manufacturing environment. 

• Ability to read and interpret engineering drawings.

• Experience setting up CNC machining centres and/or Flatbed routers.

• Good understanding of tooling, fixtures, feeds, and speeds.

• Strong fault-finding and problem-solving skills.

• Ability to work independently and as part of a team.

Desirable Requirements

• Experience using Fusion 360 or Alpha Cam software. 

• Experience with 4-axis and 5-axis machining.
