Stop losing money on
Machinist projects.
Without a signed work order, 'minor adjustments' to a CNC program turn into hours of unpaid labor. Stop letting scrap metal and vague verbal agreements eat your shop's profit margins.
Pro Tip
Include a 'Material Variance' clause stating that the client is responsible for costs associated with material defects found in client-supplied stock during the machining process.
Tolerance Disputes
Parts being rejected for subjective 'quality' issues despite meeting the blueprint's dimensional specs.
Tooling Wear and Breakage
Ignoring the cost of specialized bits or custom fixturing required for exotic materials like titanium or Inconel.
Unpaid Setup Time
Spending hours on CAM programming and machine setup only for the client to cancel or reduce the order quantity.

What is a Machinist Work Order?
A Machinist Work Order is a transactional document that authorizes specific metalworking or fabrication tasks. It outlines technical specifications (tolerances, materials), labor hours, setup fees, and payment terms, serving as a binding agreement between the shop and the client to ensure precision and payment.
Quick Summary
This guide provides a comprehensive framework for creating a Machinist Work Order. It emphasizes the importance of documenting technical tolerances, material costs, and setup time to prevent financial loss. The included template focuses on transactional clarity, covering everything from CAD revision tracking to final inspection sign-offs. By using this document, machinists can protect their business from scope creep, manage client expectations regarding material spoilage, and ensure timely payment for high-precision labor.
Why Machinists need a clear work order
For a machinist, the difference between a profitable job and a total loss is often measured in thousandths of an inch. A Work Order is your primary tool for capturing those technical requirements before the spindle starts turning. It bridges the gap between a technical drawing and a financial invoice, ensuring that machine time, specialized tooling, and setup hours are all accounted for. In an industry where raw material costs can fluctuate daily and custom jigs represent a significant investment, having a written record of the scope prevents 'scope creep' and ensures you are compensated for every cycle. It also provides a critical paper trail for quality control, documenting that the finished part meets the agreed-upon tolerances and finishing requirements specified by the client.
Do you need an invoice or a contract?
Invoices help you get paid, but they do not define scope, revisions, or ownership. For most projects, professionals use both a contract and an invoice to protect their work and cash flow. MicroFreelanceHub bundles both into a single link.
Real-world scenario
Precision Machining Inc. took an order for 100 custom stainless steel valves. The client provided the drawings but didn't specify the finish. Halfway through the run, the client demanded a mirror-polish finish, which would have added 20 hours of manual labor. Because the machinist had a signed Work Order specifying 'Standard Machined Finish (Ra 3.2)', they were able to halt production and issue a Change Order for the additional polishing costs. The client, realizing the oversight was documented, signed the update. The work order saved the shop $3,000 in labor costs that would have otherwise been eaten as a 'misunderstanding.'
🛡️ What this work order covers:
- ✓Quantity and Unit Price per part
- ✓Material Grade and Sourcing (e.g., 6061-T6 Aluminum)
- ✓Finishing Specifications (e.g., Anodizing, Powder Coating, Heat Treatment)
- ✓Inspection/QC Report and Sign-off
- ✓Scrap/Remnant Handling Policy
- ✓Final Delivery/Shipping Method
Pricing & Payment Strategy
Standard machining pricing should include a base Shop Rate (typically $85–$175/hr), a Material Markup (10-25%), and a separate Setup Fee. For high-volume production, use a tiered 'Price Per Piece' structure, but ensure the Work Order clearly defines the minimum order quantity (MOQ) and any rush fees for expedited turnaround.
Best practices for Machinists
Separate NRE Costs
Always list Non-Recurring Engineering (NRE) costs like programming and jigs as separate line items from the per-part cost.
Document Revisions
Never work off a drawing that doesn't match the revision number listed on the signed work order.
Job Description
Detailed description of the machining task, including part names, quantities, and specific operations (e.g., milling, turning, grinding, EDM). Reference specific blueprint IDs and revision numbers here.
Location / Site Details
Specify if the work is being performed at the Machinist's shop or on-site at the client’s facility. For on-site work, include requirements for power access, safety clearances, and rigging equipment.
Labor & Materials
- Material Specifications: Type, grade, and who is providing the stock (Shop vs. Client).
- Machine Labor: Estimated spindle hours and hourly shop rate.
- Setup & Programming: Costs for CAM programming, fixture building, and machine setup.
- Tooling: Charges for specialized cutters or consumables required for this job.
Start Date & Lead Time
The date work is scheduled to begin, contingent upon receipt of materials and signed authorization. Include the estimated completion date or 'Lead Time' (e.g., 4 weeks ARO - After Receipt of Order).
Completion & Inspection Terms
Define the criteria for a completed job. Include required tolerances, surface finish (Ra), and whether a formal inspection report or CMM data is required for final acceptance.
Payment Terms
Specify the deposit required (standard 50% for new clients), interim progress payments for long-term projects, and final payment terms (e.g., Net 30). Include penalties for late payments and rush fees if applicable.
Authorization Signature
By signing below, the Client authorizes the work described above and agrees to the terms and conditions. No changes to the scope will be accepted without a written Change Order.
Client Signature: ___________________________ Date: __________
Machinist Signature: ________________________ Date: __________

Frequently Asked Questions
What happens if the client-provided material is defective?
The work order should state that the machinist is not liable for machine time lost due to internal voids or defects in client-supplied stock.
Should I include CAD file versions in the work order?
Yes, always reference the specific file name and timestamp to ensure you aren't held liable for machining an outdated design.
