Strategic Case Studies & Technical Interventions
A record of engineering rigor, structural validation, and system optimization since 2004.
Case Study 01
BIW Line Throughput Recovery & Logic Synchronization
The Technical Constraint: A Tier-1 automotive welding cell was suffering from intermittent cycle-time drift. The existing PLC logic was failing to harmonize the indexing of the 7th-axis slide with the robot’s “Process-OK” handshake, leading to 12% idle time per shift.
Our Work
The Intervention:
Conducted a deep-packet inspection of the PLC scan cycle and I/O feedback loops.
o Utilized Process Simulate to identify the kinematic bottleneck in the robot’s approach vector.
o Rewrote the synchronization logic to implement a predictive handshake rather than a reactive one.
The Result:
Eliminated cycle-time drift entirely.
o Recovered 14 seconds per vehicle, resulting in an additional 18 units per day.
o Validated through 1,000 continuous cycles with zero collision triggers.
Case Study 02
Structural Bottleneck Identification in Multi-Zone Flow
The Technical Constraint: A complex manufacturing layout was hitting a “hard ceiling” at 22 JPH (Jobs Per Hour), despite the equipment being rated for 30 JPH. Previous consultants suggested adding more robots (Capital Expenditure).
Our Work
The Intervention:
Applied Throughput Intelligence models to map the “Flow Logic” across four zones.
o Identified a starvation-blocking paradox in the buffer zone between Station 20 and 30.
o Proved via simulation that the issue was not “capacity” but “sequence logic”—the system was over-prioritizing recirculating pallets.
The Result:
Stabilized output at 28 JPH without any additional hardware investment.
o Reduced buffer saturation by 40%.
o Established a Defensible Process Architecture for future scaling.
Case Study 03
Kinematic Optimization & Cycle Time Recovery
The Technical Constraint: A high-speed robotic handling cell was failing to meet its 18-second cycle time target. The system was consistently running at 21 seconds. The integrator had already attempted to increase motor speeds, resulting in excessive vibration and “Motor Overload” faults.
Our Work
The Intervention:
Conducted a Frame-by-Frame Kinematic Analysis using Process Simulate to identify redundant “Wait” states in the Handshake logic.
o Identified sub-optimal path planning where the robot was executing “Arc” movements during non-critical transitions, adding 1.2 seconds of
unnecessary travel.
o Optimized the Z-height clearance logic to allow for “Look-ahead” triggering of the gripper actuators.
The Result:
Achieved a stable 17.2-second cycle time (exceeding target by 4.4%).
o Reduced physical wear on the mechanical arm by smoothing acceleration profiles.
o Zero hardware changes required; optimization was achieved purely through path and logic refinement.
Case Study 04
Mechanical Interface Correction for BIW Fixture Stability
The Technical Constraint: A multi-part assembly fixture for a rear-underbody line was producing inconsistent parts. The issue was traced to Datum instability during the transfer phase between the manual load station and the automated
weld station.
Our Work
The Intervention:
Performed a Stack-up Analysis of the manual and automated clamping units using NX.
o Discovered a conflict in the “3-2-1” locating principle—the secondary locator was over-constraining the part, causing microscopic “bowing” when the pneumatic clamps engaged.
o Redesigned the Locating Pins and Rest Pads (Make Components) with specialized “Diamond Pin” geometry to allow for thermal expansion
during the welding process.
o Generated Detailed 2D Manufacturing Prints with strict GD&T to control the perpendicularity of the mounting faces.
The Result:
Eliminated part-bowing and achieved 100% Dimensional Compliance over a 500-part test run.
o Reduced “Rework” rate from 8% to 0.05%.
o Validated the design for long-term maintainability by using standardized “wear-and-tear” components.
Case Study 05
Buffer Strategy & System Starvation Neutralization
The Technical Constraint: A production line with 12 sequential stations was suffering from “The Ripple Effect.” A 2-minute stoppage at Station 04 was causing the entire line to stop within 30 seconds, leading to massive downstream
starvation.
Our Work
The Intervention:
Mapped the System State Logic to determine the “Actual vs. Theoretical” buffer capacity.
o Identified that the Conveyor Indexing Logic was set to “Strict Sequence,” which prevented Station 08 from working on available “Work-in-Progress”
(WIP) during upstream downtime.
o Proposed a Decoupled Flow Architecture, introducing strategic “Elasticity” in the buffer zones.
The Result:
Improved Overall Equipment Effectiveness (OEE) by 11%.
o The system can now sustain a 5-minute upstream stoppage before the final station is starved.
o Shifted the plant from “Reactive Recovery” to “Buffered Stability.”
