PART DRAWING OF SIMPLE COMPONENTS

AIM: 1. To draw the detail view of part drawing of the simple components as shown below by using pro-e

software and obtain its respective views.

2. To find the mass properties of given drawings.

COMMANDS USED:

Extrude, revolve, line, Circle, Round, Chamfer etc,

PROCEDURE:

Study the given drawing .completely and find out the front view of the given orthographic

projection.

Draw the sectional view of the front view.

Extrude the drawn section using extrude command for the given dimension.

Next select the appropriate plane and draw the other sections in similar way.

Also remove the materials where ever needed.

Using round tool we can round the edges.

Chamfering is done by the chamfer command.

Finally the part drawing is converted into the drawing format.

RESULT:

Thus the detailed view of part drawing of the simple components as shown below was drawn by using the

Pro-E software and mass properties were calculated.

Date: PROGRAMMING, SIMULATION AND PECK DRILLING & BORING

USING CNC LMILL 55 VERTICAL MACHINING CENTRE

AIM:

To write a programme for machining the given Component and execute the same

in L MILL55 Vertical Machining Centre.

TOOLS REQUIRED:

1. Tool 2. Mild Steel shaft 3.Micro meter 4. Vernier

PROCEDURE:

1.Study the Drawing Carefully to plan for the Machining operations.

2. Use the Man Machine Interface to Programme for the given Geometry

3. Set the job and the offset for the given Workpiece.

4. Use the Processor for the operation sequence and set the parameters of the operation

5. Select all the operations for the Simulation purpose and execute the program and verify

the same in L MILL55 Vertical Machining Centre.

6. Execute the Program and Remove the work piece from the Clamp.

NC CODE GENERATION USING MASTER CAM LATHE

AIM:

To generate the NC codes for given profile operation in master CAM lathe

COMMANDS USED:

Lines, Fillet, Tool Path , operation, job Setup.

PROCEDURE:

1. Using lines command draw the basic given profile in the editor by using Multi

points option.

2. Use fillet wherever needed.

3. Select Tool Path -> Rough -> Chain and select the lines at each extreme.

4. Then choose Tool path -> Job setup -> Boundary -> Parameters -> OD and Length.

5. Select Done.

CODE GENERATION :

1. Select Operation ->Regen Path -> Verify (iso) -> Post.

2. To get the code select Save.

RESULT:

Thus for given profile the NC code has been generated using master cam

lathe.
