Start With the Symptoms
Begin with what the machine, part or process is doing differently than expected.
About McMahon CNC Solutions
McMahon CNC Solutions was created to provide direct technical support for CNC manufacturing problems that affect day-to-day production.
Jacob's background includes hands-on work with CNC milling, turning, Wire EDM, grinding, machine setup, metrology, fixtures and production troubleshooting across multiple manufacturing environments.

About the Founder
Jacob McMahon brings hands-on manufacturing experience across CNC milling, turning, Wire EDM, CNC grinding, machine setup, metrology and production support.
His background has been built through direct work with machines, production teams, inspection requirements and day-to-day manufacturing challenges across multiple disciplines.
His experience also includes manufacturing software, CNC code, offsets and control-side editing, which can support troubleshooting and existing production processes when needed.
McMahon CNC Solutions was created to provide practical, direct technical support from someone who understands both the equipment and the realities of production.
Working Principles
The goal is to understand what is happening at the machine or process level and make technical decisions that are appropriate for the actual manufacturing environment.
Begin with what the machine, part or process is doing differently than expected.
Look at the machine, setup, tooling, workholding, inspection or program information connected to the issue.
Recommendations should make sense for the equipment, operators and production conditions involved.
When possible, make changes that can be evaluated clearly instead of adjusting several variables at once.
Manufacturing Approach
Technical decisions should be based on what is happening at the machine, setup and production level — and remain practical for day-to-day use.
Review setup conditions, tooling, access and operating sequence when those factors are affecting production.
Change one variable at a time whenever possible so the effect of each adjustment can be understood clearly.
Evaluate rigidity, part location, clamping, machine clearance, repeatability and operator access.
Use inspection results and dimensional trends to support technical decisions instead of relying only on assumptions.
Explain the setup, checks and reasoning operators need to understand when a corrected or revised process returns to production.
Confirm that technical changes make sense under normal operating conditions and do not create unnecessary complications.
