Description

Project Overview

A leading global automotive parts manufacturer sought to enhance the quality control (QC) process of engine cylinder head machining. The core requirement was to achieve real-time monitoring of dimensional accuracy during the milling process, reduce scrap rates, and improve production efficiency. After evaluating multiple solutions, the MMS3110/022-000 high-precision analog data acquisition module was selected as the core component of the sensing system.

Key Challenges

High Precision Demand: The dimensional tolerance of critical surfaces of the cylinder head is ±0.01mm, requiring the sensing system to have a data acquisition accuracy of at least 0.005mm.

Real-Time Response: The milling process speed is 120 pieces per hour, requiring the module to transmit data with a latency of less than 10ms to trigger timely adjustments for abnormal deviations.

Harsh Environment Adaptability: The machining workshop has temperature fluctuations (15-35℃) and oil mist interference, requiring the module to maintain stable performance under such conditions.

System Integration: Need to seamlessly connect with the existing Siemens S7-1500 PLC and MES (Manufacturing Execution System) for data sharing and analysis.

Solution Design

The MMS3110/022-000 module was integrated into a multi-point sensing system, working with 8 laser displacement sensors installed around the milling station. The key configurations and advantages are as follows:

High-Precision Acquisition: The module supports 24-bit ADC resolution and differential input, matching the laser sensors’ output (4-20mA analog signal) to achieve a measurement accuracy of ±0.003mm, exceeding the project’s requirement.

Fast Data Transmission: Equipped with Profinet industrial Ethernet interface, the module realizes real-time data transmission to the PLC with a latency of 8ms, ensuring immediate response to process deviations.

Rugged Design: The module features an IP67 protection rating, wide operating temperature range (-20-60℃), and anti-electromagnetic interference (EMI) design, adapting to the harsh workshop environment.

Seamless Integration: Compliant with IEC 61158 industrial communication standards, it directly communicates with the S7-1500 PLC via Profinet, and uploads real-time data to the MES through OPC UA protocol for trend analysis and quality tracing.

Implementation & Deployment

Hardware Installation: 6 MMS3110/022-000 modules were installed in the electrical control cabinet near the milling machines, with shielded cables connecting to the laser sensors (cable length ≤10m to avoid signal attenuation).

Software Configuration: Configured the module’s input channels, sampling rate (100Hz), and communication parameters via the manufacturer’s configuration software, and completed the PLC program debugging to set up deviation alarm thresholds.

System Testing: Conducted a 72-hour continuous test under actual production conditions, verifying data accuracy, latency, and stability.

Full-Scale Deployment: After passing the test, the system was deployed to 8 milling stations in the cylinder head workshop, covering the entire production line.

Performance Outcomes

After 6 months of stable operation, the application achieved the following results:

Scrap Rate Reduction: The scrap rate due to dimensional deviations decreased from 3.2% to 0.8%, saving approximately $120,000 in material costs annually.

Efficiency Improvement: Production efficiency increased by 18% as real-time adjustments reduced the need for post-machining rework and manual inspection.

Quality Tracing: The MES system records all dimensional data of each cylinder head, enabling full-life-cycle quality tracing and reducing customer complaint rates by 40%.

Maintenance Optimization: The module’s self-diagnostic function (e.g., sensor disconnection alarm, signal drift detection) reduced maintenance time by 30% compared to the previous system.

Customer Feedback

“The MMS3110/022-000 module has demonstrated excellent precision and stability in our production line,” said the engineering manager of the automotive parts manufacturer. “Its seamless integration with our existing system and adaptability to harsh environments have significantly improved our quality control capabilities. We plan to extend its application to the crankshaft and camshaft machining lines in the next phase.”
