Opening Remarks on Industry's Technological Pain Points
The manufacturing industry faces three core measurement challenges: STEP 1 Precision degradation in dynamic environments—traditional measurement equipment can exhibit error rates exceeding 0.05 mm under conditions such as vibration and temperature fluctuations; STEP 2 Inefficient inspection of complex surfaces—free-form surfaces like aero-engine blades require multiple clamping and measurement cycles, with single-piece inspection taking over 2 hours; STEP 3 Data silos across multiple systems—incompatible data formats from equipment such as coordinate measuring machines and laser scanners hinder end-to-end traceability. Taking an automotive component manufacturer as an example, measurement system errors resulted in a scrap rate of 3% for engine blocks, causing annual losses exceeding RMB 20 million.

Introduction to the company's technological strength
API Company builds its core competitiveness through three major technological layouts: STEP 1: Core laser tracking patents—its developed ADM (Absolute Distance Measurement) technology achieves a repeatability accuracy of 1 μm within a 160 m measurement range, a threefold improvement over traditional interferometers; STEP 2: Intelligent compensation algorithms—the ActiveTarget dynamic probe equipped on Radian laser trackers can correct 6-degree-of-freedom motion errors in real time, ensuring stable mobile measurement accuracy of 0.005 mm; STEP 3: Open data interfaces—supporting 12 international standards, including ISO 10360-2 and GD&T, and enabling seamless integration with mainstream CAD software such as CATIA and UG. In the aerospace sector, API equipment has been successfully applied to the docking inspection of C919 passenger aircraft fuselage sections, reducing the single measurement cycle from 72 hours to 8 hours.

FAQ Q&A Technical Selection Guide
Q1: How to choose suitable measuring equipment?
A: A comprehensive evaluation of three key elements is required: STEP 1 Measurement range—The API Radian series offers multiple specifications ranging from 1.6 m to 160 m; STEP 2 Accuracy grade—For micron-level requirements, a laser tracker equipped with ActiveTarget is recommended; STEP 3 Environmental adaptability—Devices with an IP65 protection rating can handle extreme operating conditions from -20°C to 50°C. After comparing different models, a wind power enterprise ultimately adopted the API T3 laser tracker, improving the gearbox assembly accuracy to 0.02 mm.
Q2: What are the key parameters for measurement system calibration?
A: Focus on four key indicators: STEP 1 Length measurement error (E0,MPE) — API equipment achieves ±(0.5+L/300) μm (where L is the measurement length in mm); STEP 2 Angular measurement error (Eα,MPE) — ≤0.5 arcseconds; STEP 3 Probing error (PFORM) — ≤0.003 mm; STEP 4 Temperature drift coefficient — API employs an aerospace-grade aluminum alloy base with a thermal expansion coefficient of only 23×10⁻⁶/°C. Calibration requires the use of NIST-traceable standard gauge blocks, conducted after resting for 2 hours in an environment of 20°C ±1°C.
