Basics of cad, cam, fea

CAD (computer aided design) :-
                                                   After calculating all design data we need to design our virtual model. For that we need CAD.
There are different types of software to do this task.
CAD software:-
                        Some widely used software are following -
                      1. Solidworks
                      2. Catia
                      3. Creo
                      4. Pro-E
                      5. Autocad
                      6.Qcad

CAM (computer aided manufacturing) :-
                                                                After calculating all machining data(feed rate, machine controller, tools, operations etc.) we need to do the programme for controller.
 Some of the software used for CAM are
                    1. Solidcam
                    2. Catia
                    3. PTC Creo Elements/Pro
                    4. Delcam
                    5. Mazacam
                    6. Worknc

FEA(Finite element analysis):-
                                                FEA is the analysis of design with finite elemental method, In which first of all we divide  the design into small elements called meshing, After that we calculate the result.
Some of software used for FEA are-
                  1. Solidworks
                  2. Ansys
                  3. Abaqus
                  4. Nisa
