CNC Specialist

Amsted Rail has an opening for a CNC Specialist.

The CNC Specialist will create, optimize, and run CNC programs using Mastercam for horizontal machining centers (HMCs), vertical machining centers (VMCs), and CNC turning centers in a hands-on production environment.

Perform efficient machine setups, prove-outs, first-article runs, and in-process adjustments to achieve safety, quality, and productivity targets.

Provide hands-on machine operation support across shifts and coach operators on best practices.

Drive cycle-time reduction, optimize tool life, and promote “quality at the source” across assigned machining equipment.

Maintain compliance with company safety, environmental, and personal growth standards.

Foster a collaborative work environment and communicate effectively with employees at all levels of the organization.

  

Safety, 5S & Continuous Improvement


* Follow and enforce PPE, guarding, and Lock‑Out/Tag‑Out (LOTO) requirements on all machining assets.


* Identify and correct unsafe machine conditions; escalate guarding or interlock concerns.


* Lead or participate in 5S events for machining cells; sustain visual standards.


* Track and improve OEE drivers: availability, performance, and quality where data is available.

CNC Programming & Optimization


* Generate, import, and post CNC programs (MasterCam or equivalent) for HMC, VMC, and turning centers.


* Edit G- & M‑code at the control to resolve issues, optimize feeds/speeds, correct toolpaths, and improve surface finish.


* Perform cycle‑time studies; recommend and implement reductions through toolpath changes, canned cycles, high‑efficiency strategies, and SMED changeover methods.


* Standardize program naming, revision control, and document control practices.


* Coordinate with Engineering on new part introductions and design‑for‑manufacturability feedback.

Machine Setup & Operation (HMC / VMC / Turning)


* Perform full setups: workholding, tooling, touch‑off, offsets, probing (if equipped), coolant and program load.


* Run first article; verify features to print, adjust tool wear and work offsets, and update control notes.


* Operate machines in production mode; monitor tool wear, chip evacuation, and repeatability across lots.


* Support quick changeovers between part numbers; apply SMED principles to reduce spindle downtime.


* Troubleshoot alarms, tool breakage, chatter, and dimensional drift; escalate when needed.



* Specify cutting tools, holders, extensions, and pull studs appropriate to material, reach, and tolerance requirements.


* Inspect and prep raw material, fixture alignments, and reference datums prior to machining.


* Support preventative maintenance (PM) and Total Productive Maintenance (TPM) tasks on assigned machine groups.

Quality & Documentation


* Perform in‑process and final inspection using precision measuring instruments (calipers, micrometers, bore ga...
