Geometric Dimensioning and Tolerancing Fundamentals: Feature Relationships

This program is part of the Fundamentals of Geometric Dimensioning and Tolerancing package. In Feature Relationships, the ten remaining geometric characteristic symbols and their categories (profile symbols, orientation symbols, location symbols, and runout symbols) are examined in greater detail using demonstrative examples to clarify their use.

Geometric Dimensioning and Tolerancing Fundamentals: Concepts and Rules

By using GD&T, a print can explicitly call out necessary tolerances in an unambiguous fashion. Using shop floor footage and animations to illustrate examples, this program introduces the viewer to GD&T rules and concepts. The 14 symbols used in GD&T are highlighted with examples to define their use.

Roll Forming

Roll forming is a high-volume production process used to produce an unlimited variety of formable cross-sections. Part of the Fundamental Manufacturing Processes Video Series, this program provides detailed information on roll forming dimensional tolerances, material straightness, camber, curve, bow and twist, roll form tooling, and roll forming machines.

Plastic Thermoforming

Plastic thermoforming is the process of producing parts by heating and shaping plastic sheet and film. This Plastic Thermoforming program highlights both cut sheet and roll fed thermoforming operations, and features details on the various thermoforming process components. The Thermoforming Process Components segment explores the materials, clamping systems, heating systems, thermoforming mold types, forming forces, and trimming processes. The basic thermoforming methods are also examined, including: drape thermoforming, cavity thermoforming, pressure thermoforming, plug assist thermoforming, and twin sheet thermoforming.

Manual Composite Layup & Spray Up

Manual composite layup and spray up are the most common methods of producing composite parts. This Manual Composite Layup & Spray Up program follows each process thoroughly, detailing each step from molds preparation through to the curing of finished layups and spray ups. The use of vacuum bag molding and autoclave molding to further consolidate layups and spray ups is also presented. This program is part of an eight program Composites Manufacturing series.

Design for Manufacture and Assembly Introduction

Design for Manufacture and Assembly (DFMA) is a proven design methodology used to optimize part costs and quality, while reducing time-to-market development. This program features an interview with Nicholas Dewhurst of Boothroyd Dewhurst. He explains the concepts and use of DFMA in product analysis to understand the drivers of cost, and the interaction of the individual pieces within the product to optimize design, manufacturability, and assembly.

Compression Molding

The use of compression molding in high volume, high quality composite parts production is featured prominently in this Compression Molding program. The various sheet, thick and bulk molding compounds are detailed as well as mold types used. The transfer molding process, which is a technological extension of compression molding is also highlighted. This program is part of an eight program Composites Manufacturing series.

Plastic Extrusion

The Plastic Extrusion segment explores components of the screw extrusion machine and common feedstock and materials. The two most prevalent plastic extrusion processes, profile extrusion and blown film extrusion, are also extensively detailed.

Extrusion Processes

Extrusion is the deformation of either metal or plastic forced under pressure through a die to create a shape. This unique Extrusion Processes program is an introduction to both plastic extrusion and metal extrusion processes. The Metal Extrusion segment looks at hot extrusion, press components, lubrication, force capacity, and the metals that are typically hot extruded. Both warm and cold extrusion processes are featured too, including indirect extrusion, combination extrusion, and impact extrusion. The Plastic Extrusion segment explores components of the screw extrusion machine and common feedstock and materials. The two most prevalent plastic extrusion processes, profile extrusion and blown film extrusion, are also extensively detailed.

Fastening and Assembly

This Fastening and Assembly program focuses on the primary fasteners and assembly processes used and includes sections on mechanical fastening, adhesive bonding, and automated assembly.
