Inspection for Quality and Field Maintenance Use Cases with Augmented Reality
Throughout a product’s lifetime, inspection is a constant.
Between verifying product quality at the time of manufacturing before shipment and ongoing aftermarket maintenance and service, inspections ensure products continue to perform as intended. The importance of inspections cannot be overstated and yet for many original equipment manufacturers (OEMs), many inspection processes are still manual, involving paper-based processes and requiring a highly trained eye.
2D digital or paper-based instructions on how to perform inspections are often ambiguous, quickly outdated, and cumbersome to flip through while trying to execute the inspection at hand. Likewise, paper-based records on the results of inspections involve tedious data entry and difficult-to-navigate storage and retrieval. These processes prove to be incapable of democratizing knowledge widely to support continuous improvement.
When it comes to quality inspections and field service maintenance inspections, the limitations of manual and paper-based processes contribute to costly rework and scrap, customer dissatisfaction, and issues with employee safety, training, and retention.
To address these challenges head-on, OEMs are leveraging augmented reality (AR) for the most complex inspection use cases––and reaping meaningful business benefits.
MANUFACTURING QUALITY INSPECTIONS
As a critical aspect of the quality control process, manufacturing quality inspections occur before
the sale and shipment of products and are instrumental in finding errors and defects before
products reach customers. Pre-assembly inspections focus on the raw materials and components
process but the product can also be inspected during and postproduction to ensure it meets
engineering specifications.
According to Quality Digest, experts have estimated that the Cost of Poor Quality (CoPQ) can range from 5% to 30% of gross sales for manufacturing and service companies.
TYPES OF INSPECTIONS
- INCOMING PARTS
- IN-LINE
- END-OF-LINE
- PACKAGING/CONTAINER LOADING
- TRAINING
TYPE OF INSPECTION: INCOMING PARTS
BEFORE
MANUAL, PAPER-BASED PROCESSES
Frontline workers need to perform testing on incoming parts and subassemblies before production to ensure specifications are met. If an issue is missed and an incorrect part is installed during assembly, it can delay production and delivery and hurt warranty costs.
AFTER
AUGMENTED REALITY
With AR, the relevant 3D digital content is anchored to the product itself. Frontline workers can quickly and easily identify component issues earlier in the assembly process before parts go into production.
TYPE OF INSPECTION: IN-LINE
BEFORE
MANUAL, PAPER-BASED PROCESSES
Frontline workers carry out visual inspections during production to ensure products are correct and meet specifications. If a defect is undetected at this stage, finding it later in the production process results in costly scrap and rework.
AFTER
AUGMENTED REALITY
Frontline workers can detect deviations and compare between as-is and as-planned through precise visual comparisons. Defects found during production are digitally captured and communicated so stakeholders can take action to prevent further issues.
TYPE OF INSPECTION: END-OF-LINE
BEFORE
MANUAL, PAPER-BASED PROCESSES
For the final audit before shipment to customers, quality engineers need to visually verify product quality with speed and accuracy. If an incorrect product makes it into the customer’s hands, it leads to costly recalls, warranty claims, and poor reputation.
AFTER
AUGMENTED REALITY
To improve accuracy and efficiency during the final audit, AR standardizes processes and provides easy to follow visual instructions based on best practices. Preventing the delivery of incorrect products protects brand reputation and customer satisfaction.
TYPE OF INSPECTION: PACKAGING / CONTAINER LOADING
BEFORE
MANUAL, PAPER-BASED PROCESSES
Using paper-based instructions, frontline workers need to confirm products are packaged according to quality specifications. Ambiguous instructions can cause improper packaging and container loading, leading to product damage, returns, and delayed deliveries.
AFTER
AUGMENTED REALITY
AR instructions provide the necessary 3D context to help frontline workers verify the correct packaging of high-value products that require sensitive handling. Proper packaging and loading are critical to protecting products and ensuring they reach their destination in as-planned condition.
TYPE OF INSPECTION: TRAINING
BEFORE
MANUAL, PAPER-BASED PROCESSES
Efficient and accurate inspection procedures require effective training and compelling learning materials. Paper-based instructions keep new workers in the classroom longer and keep training costs high, particularly for high-turnover industries.
AFTER
AUGMENTED REALITY
Easy-to-follow visual instructions can bring new workers up to speed quickly and provide more effective on-the-job training, even for complex part inspections. Improved upskilling and cross-training efforts build a more agile workforce and unlock manufacturing flexibility.
POST-MAINTENANCE INSPECTIONS
Equipment inspections can proactively identify potential issues so technicians can take action
before problems occur and disrupt customer operations. Routine and post-maintenance/repair
inspections help ensure better machine performance and prevent major repairs or equipment
failure––keeping customer downtime and service costs low.
Based on Aberdeen’s independent research, unplanned downtime, most commonly resulting from a critical piece of equipment not functioning properly, can cost companies $250K/hour in lost production, equating to more than $2 million annually.
TYPES OF INSPECTIONS
- ROUTINE MAINTENANCE
- POST MAINTENANCE
- MAINTENANCE INSPECTION TRAINING
TYPE OF INSPECTION: ROUTINE MAINTENANCE AND PREVENTATIVE CHECKS
BEFORE
MANUAL, PAPER-BASED PROCESSES
Technicians regularly inspect products under operation to determine how they are functioning. Between observing the equipment and consulting work instructions, technicians can’t work with a singular focus and potential performance issues may go undetected and cause failures, resulting in downtime.
AFTER
AUGMENTED REALITY
Technicians gain clarity with contextualized 3D markers and points of interest that inform them exactly which part they are looking at and where to find it. Increasing technicians’ accuracy prevents inspection errors and reduces costly downtime for end-customers.
TYPE OF INSPECTION: POST-MAINTENANCE, RETROFIT, AND REFURBISH
BEFORE
MANUAL, PAPER-BASED PROCESSES
Using paper-based instructions, technicians must inspect and verify that routine maintenance procedures were carried out correctly. Overlooking a critical step during this inspection puts the product at risk of failure and prolonged downtime.
AFTER
AUGMENTED REALITY
Visual cues and guidance on-demand can provide feedback in real-time to confirm every inspection step is completed correctly. Providing confirmation at the time of inspection ensures equipment is running safely and properly and reduces the need for repeat service dispatches.
TYPE OF INSPECTION: MAINTENANCE INSPECTION TRAINING
BEFORE
MANUAL, PAPER-BASED PROCESSES
New hires or customer technicians working on unfamiliar products have a higher likelihood of making inspection errors, which can result in safety and machine failure consequences. Lengthy and expensive training limits the ability to cross-train technicians on different products.
AFTER
AUGMENTED REALITY
AR-based inspection training eliminates the need for paper and enables new technicians to focus on the inspection task at hand, helping to improve accuracy and safety. AR shortens the learning curve for new or existing employees—reducing costs and increasing agility
OPTIMIZE YOUR INSPECTION PROCEDURES
How much are your paper-based inspection instructions driving up the cost of quality— or reducing the quality of your products? Augmented reality unlocks new levels of efficiency, accuracy, and transparency for manufacturing quality and field maintenance inspection use cases.
