Automotive scrap reduction

Automotive industry
Case Study

How to reduce scrap and improve performance in automotive manufacturing processes

A global manufacturer of braking systems contacted ifm because their tooling inserts kept breaking. This reduced product quality because the broken tools did not operate as precisely as necessary.

We helped the manufacturer implement a real-time monitoring and predictive maintenance system. It enables plant workers to repair or replace damaged tooling inserts before they affect product quality.

Our customer

Global manufacturer of high-performance automotive components.

  • Locations in 11 countries
  • 10,000 employees worldwide
  • $3 billion annual revenue

Leader in design, development, and production of braking systems for OEM, after-market, and racing.

Our customer

Global manufacturer of high-performance automotive components.

  • Locations in 11 countries
  • 10,000 employees worldwide
  • $3 billion annual revenue

Leader in design, development, and production of braking systems for OEM, after-market, and racing.

Results

  • Saved over $230,000 annually in scrap costs per line
  • Reduced unplanned downtime with continuous, real-time monitoring
  • Effectively reduced tool cost by increasing tool life expectancy
  • Reduced scrap from 7-10 parts per tool break to 0-1 with real-time detection
  • Solution costs $5k to $10k for 3 to 8 CNC lathes per line

The challenge

This automotive manufacturer’s production process utilizes end-of-line quality checks following their sequential lathe machining operations. During many of the operations, tooling inserts often broke, resulting in incomplete or damaged parts. These parts continued to run through the remaining operation steps before the broken tool was identified, resulting in an increased amount of finished product scrap.

  • Maintenance is reactive instead of scheduled as failures cannot be predicted
  • Loss of revenue due to stall in production because of inoperative machinery
  • Delays in maintenance due to the time it takes to submit, assign, and complete a work request

The solution – why ifm?

ifm worked with the customer to identify possible bottlenecks in their operations, common equipment failure modes or opportunities for improvement. We developed a system that included:

  • A monitoring method, which could warn of tool breakage
  • An integration path to existing machine control, enabling isolated tool tracking, monitoring, and notification
  • A process to isolate damaged parts for immediate operator evaluation
  • Continuously monitoring vibration signals using edge analytic devices
  • Individual tool monitoring with trend enabling condition-based (vs. cycle-based) replacement of worn components
  • Direct machine notification providing real time quality monitoring and the ability to quarantine parts for evaluation
  1. Early warning motor vibration threshold reached on October 18th.
  2. Failure occurred after startup on October 22nd.
  3. 10 hours of unplanned downtime.
  4. Vibration levels after motor replacement.

Technologies

Explore the underlying technologies that power this solution.

IO-Link technology is fundamental in real time monitoring and is embedded in ifm sensors. This technology allows the sensors to communicate the health and condition data via ethernet for processing. IO-Link communication provides fully digital data, resulting in higher quality measurements eliminating analog conversions.
