Fusion 360 3D modeling
With Fusion 360 3D modeling software or any other software, you will implement a product assembly, which is composed of several parts. For Computer Integrated Manufacturing you need to submit an assembly design with at least 6 DIFFERENT parts. You should demonstrate the use of as many modeling techniques (such as extrude, revolve, mirror, pattern, holes, etc) as possible. In addition, you will:
a) Select one part from your design suitable for CNC milling process and generate a
manufacturing process plan for it, including CNC milling program generated with Pro/Manufacturing.
b) Improve the assembly with DFM/DFA methodologies. The purpose of DFM/DFA is to improve the current design and make it easier for manufacturing and assembly.
• For Computer Integrated Manufacturing, you need to improve it with Design for Assembly (DFA) methods.
You need to submit a one-page project abstract, with the following component:
1. Project Objectives
a. What product assembly is going to be modeled and analyzed?
b. List the parts in this assembly.
c. Select parts that will be improved by doing DFM/DFA analysis.
Sample Solution
The project objective is to use the Fusion 360 3D modeling software and other software such as Pro/Manufacturing, to model and analyze a product assembly composed of 6 different parts. Through this analysis, I will generate a manufacturing process plan for one part in particular that is suitable for CNC milling, improve the assembly using Design for Assembly (DFA) methodologies and demonstrate the use of many modeling techniques.
The product assembly being modeled consists of six individual parts that are designed to be CNC milled out of aluminum. The parts include two long-bodied panels with smaller protrusions on their sides, connected together by four smaller rectangular pieces that fit into slots cut into each panel’s sides. All components must assemble easily so as not to require too much force or precision equipment during the manufacturing process.
By utilizing various CAD tools such as extrude, revolve, mirror and pattern commands along with drill holes and other features associated with machining operations; I can create an accurate digital representation of my desired design before it is machined out from actual material stock. Furthermore by designing up front for assembly specific considerations like snap fits; living hinges etc); I can ensure that once all components have been manufactured they come together without error while still allowing them to be taken apart later in the event any repairs are needed in the future.
Finally, through successful implementation of these strategies combined with a thorough understanding of best practices regarding tool selection; feeds & speeds; CAM post processing etc—I will be able to develop a reliable CNC program capable producing this device accurately and efficiently meet its intended function within acceptable tolerances.
understudies. Given the expected worth of such figures propelling scholastic achievement and hence impacting results like maintenance, wearing down, and graduation rates, research is justified as it might give understanding into non-mental techniques that could be of possible benefit to this populace (Lamm, 2000) . Part I: INTRODUCTION TO THE STUDY Introduction The country is encountering a basic lack of medical care suppliers, a deficiency that is supposed to increment in the following five years, similarly as the biggest populace in our country's set of experiences arrives at the age when expanded clinical consideration is essential (Pike, 2002). Staffing of emergency clinics, centers, and nursing homes is more basic than any time in recent memory as the enormous quantities of 'people born after WW2's start to understand the requirement for more continuous clinical mediation and long haul care. Interest in turning into a medical caretaker has disappeared as of late, presumably because of the historical bac
