Cycle-Time Reduction
Evaluate toolpaths, cutting parameters, process sequence, and machine utilization to uncover avoidable time.
Independent CNC Process Optimization
More profitable production from the equipment you already own.
Practical manufacturing process assessments and targeted improvements for machine shops that want better throughput, lower cost per part, and more reliable production.
Request a Process Assessment →Independent advice. No tooling or equipment sales commissions.Where value is created
Improve the process. Not just the cutting speed.
Every operation affects the economics of the finished part. We examine the entire process to identify improvements that make sense on your floor.
Setup & Fixture Optimization
Assess workholding, part handling, changeovers, and opportunities to consolidate operations.
Cost per Conforming Part
Consider tooling cost, tool life, scrap, consistency, and throughput together—not in isolation.
Process Engineering
Review machine selection, operation planning, and manufacturability for complex machined components.
Tooling & Cutting Strategy
Identify opportunities to improve tool application, chip control, process stability, and repeatability.
Independent Assessments
Receive an outside technical perspective and a prioritized written action plan before committing to changes.
How engagements begin
Assessment first. Implementation by agreement.
The initial engagement is a focused review of your existing process—not an open-ended programming contract.
I don't sell tooling. I optimize manufacturing processes.
- 01 — Define the opportunityDiscuss the part, production challenges, and scope of the assessment.
- 02 — Evaluate on siteReview the process, observe production where feasible, and collect relevant data.
- 03 — Deliver findingsProvide a written summary with prioritized recommendations and potential next steps.
- 04 — Scope further work separatelyAny programming, fixture design, or implementation is proposed and approved as a separate project.
Experience on the shop floor
Technical judgment grounded in real production.
Founded by Christopher McCallum, McCallum Manufacturing Consulting draws on extensive hands-on CNC machining and programming experience, including complex multi-axis work, aerospace components, process planning, and workholding.
The objective is straightforward: find practical, measurable opportunities to improve manufacturing performance while respecting quality requirements and the realities of production.
Based in southeastern Michigan. On-site engagements available by arrangement.
