Sheet metal product manufacturing industries have been mainly using 2D drawings so far. Most of the CAD/CAM softwares for sheet metal are designed to work mainly with 2D drawings, which require substantial user interaction at various stages thus having an adverse effect on productivity. Adoption of 3D modeling in this industry is on the rise now. 3...
Technical Report

Additive Manufacturing has become a buzz word in today’s manufacturing world. It has gone through tremendous improvements over the past few decades and has matured from simple prototyping to actual manufacturing and tooling. Various methods have emerged like Fused Deposition Modeling (FDM), Stereolithography (SLA), PolyJet (3DP), Selective Laser Si...
Technical Report
Full-text available
To cope up with the global competition, developing expertise on lowering product cost and quality manufacturing are going to be essential. Designs need to contain only essential functional features and care needs to be taken to make the designs manufacturable using cheaper manufacturing processes and with less scrap and rejections. This will not on...
Technical Report
Full-text available
Cost reduction seems to be today’s mantra as competition is increasing on a global level. To sustain in the market, every aspect that accounts to cost has to be studied thoroughly and measures have to be taken to reduce unwanted elements of design to reduce the product cost. Material cost and manufacturing cost are two major elements that influence...
Article
Both feature recognition and reasoning are needed for automating manufacturing planning activities for 3D sheet metal components. The feature reasoning system proposed here generates manufacturing information (e.g. flat pattern, locations of various features, internal cuts and blank profiles, type of tools required, operation sequence, bending sequ...
Article
To automate planning activities in a computer integrated manufacturing environment, an integrated system of feature recognition and reasoning is essential. An attempt is made in the present work to develop such a system for 3D sheet metal components. Though certain part-modellers use feature-based methodology, they lack the information required for...
Article
Bending is one of the vital operations to obtain a three-dimensional (3D) shape in a sheet metal component. While planning for its manufacture, it is important to select proper tools, tool stages and sequence for collision-free bending at every stage. Collinear bends can be performed in a single operation. Tools and tool stages can be reused in a s...
Conference Paper

Manufacturing of sheet metal component varies to a vast extent in terms of the forming methods and in turn the manufacturing planning when compared with prismatic or cylindrical components. Sheet metal bending is one of the widely used methods in sheet metal processing. During progressive bending to form a 3D component from the flat pattern, any ar...

The type of material handling systems that are used in a firm determines the layouts of most of the manufacturing firms. The layouts are normally designed to facilitate easy handling and to increase the utility of the material handling systems. Automated guided vehicles (AGVs) are flexible automated material handling systems that can be programmed...

The design data of components in most of the industries are still in orthographic representations. Interpretation of orthographic projections requires skill whereas 3D models provide concise and unambiguous representation of part geometry. This necessitates the existing drawings to be converted into 3D models. A system that can automatically transf...

A linear programming problem (LP) deals with determining optimal allocations of limited resources to meet the given objectives. The objectives are usually maximizing profit, minimizing total cost, maximizing utility etc. In general, LP problems are solved by two methods. One is algebraic method (Simplex method) and the other one is graphical method...

Adhesive bonding is gaining importance as they are lightweight and less costly and even the use of load bearing adhesives are on the increase. Nowadays adhesives are commercially available for both industrial and domestic applications. Any adhesive cannot be used for a given bonding requirement as the type of materials that can be joined by an adhe...

In most of the metal forming and plastic industries, product name or name of the manufacturing firm is normally engraved on their products. This necessitates these names to be engraved on the dies. Dies are generally manufactured by die-sinking process and conventional machining process but recently the use of CNC machines in die-making industry is...
Article
Feature Based System (FBS) capture information regarding manufacturing, function, and assembly at the design stage. This approach generates simple and easy to use database, which is necessary to integrate CAD/CAM. Most of the FBS use solid models, as they provide the most concise representation of part geometry. However special hardware and softwar...
Article
Flat pattern development of sheet metal components is a prerequisite for sheet metal fabrication and it also facilitates development of process plans. Commercial softwares for flat pattern development are too expensive and they often require a 3-D model of the component. In fact, most of the component drawings exist as orthographic projections in t...

ALARVY is a simple 3D CAD modeler for creating turned parts. Unlike generic CAD modelers, which are suitable for creating any type of parts, ALARVY is a specific CAD modeler with features specific to create turned parts.This reduces lot of unwanted functionalities and makes the user interface very simple. ALARVY helps you to create detailed 3D models faster than any other modeler. ALARVY reduces number of clicks extensively to create models with Auto-dimensioning, Auto-constraints, Auto-expanding grid, Auto-view change for sketching, Sketch self intersection checks, Smart checks for feature creation. While creating features, ALARVY automatically changes view for sketching. It applies auto-constraints like horizontal constraint, vertical constraint and grid snap to make sketching faster. Grid expands automatically when sketch points are outside grid limits. While sketching it auto-checks for sketch self-intersecton and invalid sketching profiles. It auto-dimensions the features thereby improving productivity to a great extent. ALARVY CAD files are saved in simple json format and is an open file format based on feature data rather than B-Rep data. This makes ALARVY CAD files smart rather than dumb 3D models. This helps to facilitate easy integration with any CAM software and apply CNC routines specific to features. ALARVY - 3D CAD Modeler for Turned Parts is a specific 3D CAD modeler with features specific to create turned parts that can be manufactured in lathes and turning centres. ALARVY Turn module comes with the following features : Revolve, Step, Fillet, Grooves (Rectangular, Trapezoidal, Filleted Rectangular and Filleted Trapezoidal), Holes (Simple, Tapered, CounterSink, CounterDrill and CounterBore).
