About This Project

CNC Optimization is a free calculator platform developed by an individual software developer to help manufacturing professionals make informed decisions about equipment selection, cost analysis, and production planning. The platform provides 11 professional-grade calculators covering the complete lifecycle of CNC equipment investment and operation.

Development Background

This project was commissioned by OPMT Laser, a CNC laser equipment manufacturer. The calculators are now freely available to all manufacturers worldwide, regardless of equipment brand or supplier. Our goal is to provide transparent, standards-based tools that help manufacturers optimize their operations and make data-driven investment decisions.

What's Included

All calculations are based on internationally recognized manufacturing standards and industry best practices:

ISO 230-2 (Geometric and Positioning Accuracy)

Our equipment selection and precision calculators use ISO 230-2 standards for positioning accuracy, repeatability, and geometric tolerance verification. This ensures compatibility scoring aligns with industry-accepted accuracy classifications (±3-5μm for high precision, ±8-10μm for standard precision).

GB/T 17421 (Maintenance Standards)

Maintenance interval calculations follow GB/T 17421 Chinese national standards for CNC machine tool maintenance, including preventive maintenance schedules, component lifecycle expectations, and failure mode predictions. These are widely adopted in Asian manufacturing and increasingly referenced globally.

MACRS & IRS Guidelines (Tax Depreciation)

Tax and depreciation calculators implement Modified Accelerated Cost Recovery System (MACRS) as defined by US IRS Publication 946, with support for Section 179 expensing and regional variations. We also support straight-line and declining balance methods common in EU and other jurisdictions.

Industry Benchmarks

Our OEE calculations, bottleneck analysis, and TCO models reference data from:

• MachineMetrics - OEE benchmarking and IoT monitoring standards
• Theory of Constraints (TOC) - Bottleneck identification methodology
• SMED (Single-Minute Exchange of Dies) - Setup time reduction strategies
• ProNest - Material nesting and waste minimization benchmarks

Transparent Formulas

Every calculator uses documented formulas that can be verified against industry standards. For example:

• Laser Power: Required Power (W) = Material Factor × √Thickness (mm)
• OEE: Availability × Performance × Quality (each 0-100%)
• TCO: Initial Cost + Operating Costs - Salvage Value
• NPV: -Initial Investment + Σ(Cash Flows / (1 + Discount Rate)^Year)

Uncertainty Quantification

We provide uncertainty ranges (typically ±5%) where calculations depend on variable factors like material grades, operator skill, or maintenance quality. This helps you understand the confidence level of each estimate.

Real-World Validation

Calculator outputs are cross-referenced with:

• Equipment manufacturer specifications (e.g., OPMT CNC laser systems)
• Industry case studies and published ROI analyses
• Manufacturing operations cost surveys
• Academic research on production optimization

Client-Side Processing

All calculations execute entirely in your web browser using JavaScript. Your input data never leaves your device - there are no server-side calculations or data transmissions to process your numbers.

No Data Collection

We do not collect, store, or analyze your calculation inputs or results. The website uses minimal analytics (page views only, no user tracking) to understand which calculators are most useful.

Local Auto-Save

Calculator forms auto-save to your browser's local storage to prevent data loss on page refresh. This data stays on your device and can be cleared through browser settings at any time.
