Knowledge Base for Product Owners
TL;DR
This comprehensive guide explains essential engineering terminology that product owners need to understand when working with technical drawings. From projection methods and GD&T symbols to surface roughness and tolerance specifications, each concept directly impacts manufacturing costs, quality requirements, and production feasibility. Understanding these terms enables better communication with engineering teams, more accurate cost estimation, and informed decision-making throughout the product development process.
Understanding basic engineering terms when extracting information from technical drawings is important both for efficient use of time and for keeping track of work. Technical drawings contain a wealth of manufacturing information encoded in symbols, annotations, and standardized notations that directly impact production costs, quality requirements, and manufacturing feasibility.
Werk24 has developed a comprehensive knowledge base for the product owners, describing various terminologies in mechanical engineering. In this way, we thrive to enrich the mechanical engineering background of our product owners by assisting them to understand these complex terms straightforwardly.
Imagine extracting information from an engineering drawing where you came across a new symbol. It would be inconvenient to search for these small details on Google. Werk24 provides you with a platform where these small details are categorized and can be accessed with ease.
Why Engineering Knowledge Matters for Product Owners
Product owners who understand engineering terminology can make more informed decisions about manufacturing requirements, cost implications, and quality specifications. When you can interpret the technical language of drawings, you can better communicate with engineering teams, validate requirements, and identify potential production challenges early in the development process.
Werk24 knowledge base helps product owners to grasp the importance of the information and explains which aspects can have a business impact. For example, we recommend our product owners to use IT Grades for Tolerancing and N Grades for Surface Finish, as these parameters make life easier for the product owners and their developers.
For developers, we have detailed documentation providing in-depth insights into the mechanical principles and their application.

Detailed Explanations of Key Engineering Concepts
Projection Methods: The Foundation of Technical Communication
Projection methods are fundamental to how engineers communicate 3D designs on 2D drawings. First Angle Projection, predominantly used in Europe and Asia, places the object between the observer and the projection plane. Third Angle Projection, standard in North America, positions the projection plane between the observer and the object. This difference affects how views are arranged and interpreted, making it crucial for product owners to understand which standard applies to their drawings to avoid costly manufacturing errors.
Measures: Translating Design Intent to Manufacturing Reality
Dimensional measurements on technical drawings serve as the blueprint for manufacturing operations. These include not only basic length, width, and height dimensions but also angular measurements, coordinate dimensions, and reference points. Each measurement type has specific implications for manufacturing processes, tooling requirements, and quality control procedures. Product owners who understand measurement hierarchies can better assess manufacturing feasibility and cost implications.
Thread Specifications: Critical for Assembly and Functionality
Thread callouts contain essential information including thread type (metric, unified, pipe threads), nominal diameter, pitch or threads per inch, thread class, and engagement length. These specifications directly impact manufacturing processes, tooling selection, and assembly procedures. Understanding thread requirements helps product owners evaluate supplier capabilities, assess manufacturing complexity, and anticipate potential assembly challenges that could affect project timelines and costs.
Geometric Dimensioning and Tolerancing: Precision Manufacturing Language
GD&T symbols provide a precise method for communicating manufacturing requirements that go beyond basic dimensional tolerances. These symbols define form tolerances (straightness, flatness, circularity), orientation tolerances (perpendicularity, parallelism, angularity), location tolerances (position, concentricity), and runout tolerances. Each symbol has specific manufacturing implications and cost considerations that product owners need to understand for effective project management.
Edge Treatments: Balancing Function and Manufacturing
Edge specifications including chamfers, fillets, and break-edge callouts affect both part functionality and manufacturing processes. Sharp edges may require deburring operations, while specific chamfer angles might need dedicated tooling. Fillet radii can impact machining strategies and tool selection. Understanding these requirements helps product owners anticipate additional manufacturing operations and associated costs.
Surface Roughness: Quality Requirements with Cost Implications
Surface finish specifications range from rough machined surfaces to precision ground or polished finishes. Each level of surface quality requires specific manufacturing processes and tooling. Understanding the relationship between surface roughness values and manufacturing methods helps product owners make informed decisions about quality requirements versus cost considerations.
Title Block Information: Project Management Essentials
Title blocks contain critical project information including part numbers, drawing numbers, revision levels, material specifications, drawing scales, and approval signatures. This metadata is essential for configuration management, change control, and ensuring manufacturing teams work with current drawing revisions. Product owners rely on this information for project tracking and supplier communication.
Tolerance Analysis: Balancing Function and Cost
Tolerance specifications define acceptable manufacturing variation and directly impact production costs. Tighter tolerances require more precise manufacturing processes, specialized tooling, and additional quality control measures. Understanding the relationship between tolerance requirements and manufacturing costs helps product owners optimize designs for both functionality and manufacturability.
Radius Specifications: Manufacturing Process Implications
Radius callouts define curved features that require specific manufacturing approaches. Small radii might need specialized end mills, while large radii could require form tools or multiple machining passes. Understanding radius requirements helps product owners assess manufacturing complexity and potential tooling costs, particularly for custom or non-standard radius values.
