Below, we explore different facets of manufacturing experience, dissecting its overarching principles and delving into niche subtopics.

The early 1800s marked a significant turning point in manufacturing with the advent of the factory system. Before this period, most goods were produced by skilled artisans in small workshops or at home. The factory system revolutionized this process by bringing together large numbers of workers under one roof, utilizing machinery to increase productivity. This system was pivotal in transitioning from handcrafted to machine-made goods, laying the foundation for what we now recognize as mass production.

Manufacturing overhead, also known as factory overhead, factory burden, or production overhead, refers to all the indirect costs associated with producing a product. These are costs that are not directly tied to the production process, like raw materials or direct labor, but are essential for the manufacturing process.

Overall Equipment Effectiveness (OEE) is a key performance indicator (KPI) used in the manufacturing industry to measure the efficiency and effectiveness of a manufacturing process. It provides a comprehensive framework for evaluating how well a manufacturing operation is being utilized compared to its full potential. OEE considers three primary components: Availability, Performance, and Quality.

Manufacturing overhead, also known as factory overhead or production overhead, encompasses all the indirect costs associated with the manufacturing process. These are costs that are not directly tied to the production of specific goods but are necessary for the overall manufacturing operations to run smoothly. Manufacturing overhead can significantly impact a company's financial health and product pricing strategy.

Manufacturing is the process of converting raw materials into finished goods through the use of tools, machinery, and labor. This fundamental practice is a cornerstone of modern economies, enabling the mass production of products ranging from everyday household items to complex machinery and electronics. The term "manufacturing" encompasses a wide array of activities, techniques, and industries, each contributing to the creation of goods that meet consumers' needs and preferences.

Additive Manufacturing (AM), often referred to as 3D printing, is a transformative approach to industrial production that enables the creation of lighter, stronger parts and systems. AM uses computer-aided design (CAD) software or 3D object scanners to direct hardware to deposit material, layer upon layer, in precise geometric shapes. This process contrasts with traditional, subtractive manufacturing methods, which often involve cutting away material to achieve the desired form.

Lean Manufacturing is a systematic method for waste minimization within a manufacturing system without sacrificing productivity. Originating from the Toyota Production System (TPS), Lean Manufacturing focuses on creating more value for customers with fewer resources. The primary goal is to optimize the flow of products and services through value streams that flow internally across technologies, assets, and departments to customers.

Manufacturing is the process of transforming raw materials into finished goods through the use of machinery, tools, and human labor.
