CNC Programmer - SolidWorks & Mastercam

CNC Programmer – Mastercam

For over 140 years, Horsburgh & Scott has been a leader in the design, manufacture, and repair of custom industrial gears, gearboxes, and power transmission equipment. We are seeking an experienced CNC Programmer to join our Manufacturing Engineering team andhelp produce some of the largest, most complex precision components in the industry.

Position Summary

The CNC Programmer develops and optimizes older and newer CNC programs using Mastercam, 2020 and version and newer and SolidWorks to manufacture precision components for industrial gearboxes and gearing systems. This position works closely with Engineering, Production, and Quality to improve machining efficiency, reduce setup time, and ensure the highest level of quality.

What You'll Do

• Create CNC programs using Mastercam from SolidWorks models and engineering drawings.
• Develop machining strategies, toolpaths, setup sheets, and tooling requirements.
• Optimize cycle times, feeds, speeds, and cutting tool performance.
• Support production by troubleshooting and improving existing CNC programs.
• Collaborate with machinists, engineers, and quality personnel to improve manufacturing processes.
• Design and improve work holding and fixturing.
• Verify programs through simulation and machine proof-outs.
• Support Lean Manufacturing and continuous improvement initiatives.

Equipment You'll Support Programming experience with large CNC machine tools is preferred, including equipment like:

• Giddings & Lewis Horizontal Boring Mills
• Schiess Horizontal Boring Mills
• G & L Vertical Turning Centers
• Farrell Machine Tools

Key Responsibilities

• Read and interpret blueprints, engineering drawings, setup sheets, and work orders to determine machining requirements and sequences
• Perform full machine setups including tooling selection, fixture installation, work holding, and workpiece alignment for large-scale components
• Operate horizontal boring mills to perform facing, boring, drilling, contouring, and precision finishing operations on large castings and fabricated assemblies
• Set up, load, and execute CNC programs; make at-machine edits or adjustments as required to meet dimensional and surface finish requirements
• Adjust machining parameters such as speeds, feeds, depth of cut, and tool offsets to maintain accuracy, efficiency, and tool life
• Monitor machining operations to ensure conformance to specifications, making real-time corrections as needed
• Inspect machined components using precision measuring instruments including micrometers, calipers, bore gauges, dial indicators, and height gauges
• Perform in-process quality checks and verify critical dimensions to ensure compliance with engineering tolerances
• Maintain machine cleanliness and perform routine preventive maintenance and daily operator care
• Document production data, inspection results, and any nonconformances; promptly communicate machine or quality issues to supervision
• Collaborate with quality, engineering, and production teams to ensure proper interpretation of requirements and continuous process improvement
• Adherent to all safety procedures, including proper rigging and handling of large and heavy components

Qualifications

• Associate degree in Manufacturing Engineering Technology, Mechanical Engineering Technology, CNC Programming, or equivalent experience.
• 10 years of Machining and control experience on the Boring Mills and Lathes
• 5 years of CNC programming experience with Siemens, Fanuc, G & L 800 and G & L 8000 controls
• Proficiency with Mastercam, 2020 and newer version and SolidWorks.
• Strong knowledge of G-code, blueprint reading, GD&T, machining processes, tooling, and fixture design.
• Strong Problem-solving skills
• Experience with large-part machining or heavy industrial manufacturing preferred.
• Assist with operating software updates as needed
• This position requires strong mechanical aptitude, attention to detail, and the ability to work independently on large-scale, high-value components in a heavy industrial manufacturing environment.
• Gear manufacturing experience is a plus

Why Horsburgh & Scott?

• Work on large, custom-engineered industrial equipment—not high-volume production parts.
• Various machine and gear manufacturing equipment.
• Stable company with over 140 years of industry leadership.
• Competitive compensation and comprehensive benefits.
• Opportunities for professional growth and career advancement.
