Senior Machinist (Machinist III)

This role is for a Senior Machinist (Machinist III) who can program, set up, and machine complex 3D parts on a 4‑axis horizontal machining center, and who has hands‑on experience with Renishaw probing, including creating and modifying probing routines and subroutines/macros.

Position Overview:
We are seeking a highly skilled 4‑Axis CNC Programmer/Machinist to support complex, high‑value machining work requiring strong process ownership, advanced setup strategy, and in‑process probing/verification.

This role is centered on a Doosan NHP 8000 horizontal machining center with pallet changing and a B‑axis rotary table. The successful candidate will own jobs end‑to‑end — CAM programming fixturing setup probing machining inspection optimization — in a custom, non‑production environment.

REQUIRED EXPERIENCE (Non‑Negotiable):
Your resume must clearly demonstrate most of the following:
CNC Programming (Required)
Mastercam (preferred) or comparable CAM software (NX, Fusion, PowerMill, etc.)
Creation and optimization of 3D toolpaths for complex geometry
Experience programming 4‑axis machining using B‑axis rotation
Ability to post, prove out, and safely run new programs
Solid understanding of work offsets, tool control, and collision avoidance
4‑Axis / Complex 3D Machining (Required)
Hands‑on experience machining complex 3D parts on horizontal machining centers
Effective use of 4‑axis positioning (B‑axis) to access multiple faces and reduce setups
Ability to hold tight tolerances and produce high‑quality surface finishes
Advanced blueprint reading and GD&T
✅ Renishaw Probing + Routine Programming (Required)

Hands‑on use of Renishaw probing systems for:
part pickup and alignment
work offset setting and updating
bore/boss location verification
in‑process inspection and verification checks
Ability to create and edit probing routines
Experience writing or modifying probe subroutines/macros to improve repeatability and reduce setup time
✅ Workholding & Process Ownership (Required)

Experience designing and building custom fixtures
Comfortable owning jobs independently from programming through completion
Horizontal machining experience strongly preferred
Experience using pallet‑changing machines a plus

Key Responsibilities
CNC Programming & 4‑Axis Machining
Program and optimize parts using Mastercam or equivalent CAM software
Machine complex parts using 4‑axis positioning on a horizontal machining center
Develop efficient machining strategies to reduce setups and improve accuracy
Prove out programs and optimize feeds, speeds, and toolpaths
Generate tooling strategies appropriate for complex geometry

Renishaw Probing & Automation:
Use Renishaw probing for setup, alignment, and verification
Write and modify probing routines and subroutines/macros for:
automated setup routines
work offset updates
feature verification and inspection checkpoints
Adjust machining strategy based on probing and inspection results

Fixturing & Setup Strategy:
Design and build fixtures for rigidity, accuracy, and repeatability
Plan setups to minimize part handling and eliminate secondary operations
Manage deflection, distortion, and access challenges through smart workholding

Troubleshooting & Optimization:
Diagnose and correct chatter, surface finish issues, tool wear, and alignment problems
Modify programs and processes based on inspection data
Improve repeatability, first‑article success, and cycle efficiency

Senior‑Level Expectations:
Serve as a technical resource for CNC machining and probing practices
Support continuous improvement in CAM workflows and shop standards
Provide input on tooling and cutter selection for upcoming work

Final hourly rate is based on demonstrated:
CAM programming depth
4‑axis machining experience
Renishaw probing and routine/subroutine proficiency
Ability to independently manage complex jobs
How to Apply (Required Resume Details)

To be considered, your resume must clearly include:
CAM software used (Mastercam or equivalent)
Description of 4‑axis machining experience
Examples of complex 3D parts you’ve programmed and machined
Renishaw probing experience and what it was used for
Whether you’ve written or edited probe routines/subroutines/macros
Machine types operated (horizontal machining centers preferred)
