Time-of-Flight Diffraction (TOFD) is a highly accurate ultrasonic technique for flaw detection and sizing. It uses separate transmitting and receiving probes. Instead of measuring the amplitude of a strong reflection from the face of a flaw, TOFD measures the arrival time of the much weaker waves diffracted from the flaw's upper and lower tips, enabling precise through-wall size measurement.

The Buying Center is a model representing all individuals and groups within an organization who participate in a purchase decision. It's not a fixed unit but a set of roles assumed by different people for different purchases. These roles include initiators, users, influencers, deciders, approvers, buyers, and gatekeepers, each impacting the final decision through their specific function and authority.

Total Quality Management (TQM) is a management philosophy where all members of an organization participate in improving processes, products, services, and the culture in which they work. It aims for long-term success through customer satisfaction. TQM integrates quality-discipline into the culture and activities of a company, moving beyond simple product inspection to a holistic, organization-wide approach.

Successful Takt time implementation requires a highly stable production environment. Common challenges include managing machine downtime, ensuring consistent quality to avoid rework, and balancing lines that produce multiple products with different work contents (mixed-model lines). Without addressing these sources of variability, a Takt-driven system can be brittle and fail to meet demand consistently.

Laser transmission welding joins two overlapping thermoplastic parts by passing a laser beam through a laser-transmissive upper part to a laser-absorbent lower part. The absorbed laser energy heats and melts the interface. Clamping pressure fuses the molten layers, and upon cooling, a strong, clean weld is formed. This method is precise, non-contact, and creates minimal thermal stress or particulate contamination.

Solid modeling in CAD represents objects as unambiguous, voluminous 3D shapes. Two primary techniques dominate: Boundary Representation (B-rep), which defines a solid by its bounding surfaces (faces, edges, vertices), and Constructive Solid Geometry (CSG), which builds complex shapes by applying Boolean operations (union, subtract, intersect) to simpler primitive solids like cubes, spheres, and cylinders.

A design methodology where 'X' represents a specific product life cycle objective. DFX encompasses a collection of guidelines and techniques aimed at optimizing a product's design for a particular goal, such as manufacturability (DFM), assembly (DFA), reliability (DFR), or sustainability (DfS). This proactive approach addresses potential issues early in the design phase, reducing costs and improving quality.

To address the inability of different CAD systems to share data, neutral file formats were created. The Initial Graphics Exchange Specification (IGES), developed in the late 1970s, was an early attempt. It was later superseded by the more robust and comprehensive STEP (Standard for the Exchange of Product model data, ISO 10303), which can represent full 3D models, assembly structure, and metadata.

A patented form of ecological wastewater treatment and water reclamation system developed by Dr. John Todd. It uses a series of diverse ecosystems, including bacteria, algae, plants, snails, and fish, within controlled environments like tanks or greenhouses, to purify water. The system mimics the natural purification processes of wetlands and other aquatic ecosystems but in an intensified, engineered setting.

High-precision CNC machines employ a closed-loop control system to ensure accuracy. This system uses feedback devices, such as rotary encoders on servomotors or linear scales on the machine axes, to continuously monitor the machine's actual position. The controller compares this real-time feedback with the commanded position from the program and makes immediate corrections, compensating for errors.
