Component 1:

Industrial Robot Arm

Task:- To pick any Robot Arm Design from Online and remake it with visible modifications using advanced features

    • For this purpose, I chose an Industrial Robot arm assembly design dimensions from YouTube.
    • Made Several modifications to make it suitable as per DFM.
    • Modifications included:-
    • Draft of several faces, Fillets at external corners,
    • Hinge pins for Joining, Limiting the rotating angles,
    • Removal of excess materials,
    • Change of gripper Jaws geometry

Component 2:

Bicycle

Task:- To make a whole assembly without seperate part files & use smart toolbox

    • For this purpose, I was provided several 3D model design of cycle parts.
    • I had to re-make them and save internally in a single assembly file.
    • Then for sprocket, bearings and axle nuts & bolts, I used Toolbox Library feature of Solidworks.
    • Used configurations to create a same component twice but with slight modification in elements (Wheels).
    • Also learnt to use Texture appearance to create a close to realistic view of component

Component 3:

Shaper

Task:- To make whole shaper assembly and modify dimensions & Geometry for successful mating with toolbox components

    • For this purpose, I was provided a drawing sheet with all required sketches.
    • The drawing sheet had detail drawing of all components except for standard nuts & Bolts.
    • I was use toolbox for bearings, nuts, bolts, circlip & Gears.

Minimum Assembly files

Using Weldment cutlist and unmerged solid bodies in party file itselft to increase productivity.

Equation driven

Try to figure out key dimension of the part on which all are dependent, then create other dimension in equation form of these variables and constraints

Use configurations

For similar elements with slight variations, always use configurations to minimize total part files and allow better data management and modifications

Designing Strategy

Used

21 of 27

Basic Shape & Size first

Always design based on minimum and maximum possible dimensions as per set-up requirement

Simulation-based dimensions

After providing for Basic Shape, simulate the force analysis and optimize as required.

Material & Time Saving technique

Use of aesthetic Fillets at suitable corners depending on mfg. process to reduce time and/or material consumption.

Designing Strategy

Used

22 of 27

Changes in Drafting Operation

  • Creation of Templates first in all size.
  • Creation of Sheet format with drafting standard for pre-made.
  • Using Sketchblocks for fixed entities in format.

Global variable based Equation driven Designs

  • Identifying the independent or deciding dimensions.
  • Setting them as Global Variables at beginning of modelling.
  • Making dimensions in the form of equations having these global variables.

Modified Gearbox & Motor support Bracket

  • Use of standard part & Gussets.
  • Simplification of design.
  • Reduction of mfg. Time & Cost.

WORKAROUNDS

    • Save Bodies as individual part files, then link to custom property of each.
    • Make Global variables part of equations at beginning of design.
    • Use standard components or parts with modifications.

PROBLEM

    • Title-Block Doesn’t auto-update for cut-list bodies.
    • Too much effort & time in changing the equations for new design.
    • Too much complex & hard to manufacture design.

Solidworks

Centric
