2. CERTIFICATE

3. SolidWorks is a  solid modeling computer-aided design (CAD) and computer-aided engineering(CAE) computer program that runs on Microsoft Windows . SolidWorks is published by Dassault Systèmes . More than 3,246,750 product designers and engineers worldwide, representing  240,010 organizations , use SOLIDWORKS to bring their designs to life–from the coolest gadgets to innovations that deliver a better tomorrow.

4. SolidWorks for :- Solidworks is used by students , designers, engineers and others professionals to produce simple and complex part, assemblies and drawings. Designing in a modeling package such as a solidworks is beneficial because because it saves time, efforts, and money that would otherwise be spent prototyping the design . Solid works is a full parametric software.

5. SOLIDWORKS USER INTERFACE

6. Module's of SolidWorks :- Sketcher Part Modeling Surface Molding Sheet Metal (Bending Allowance, k-factor) Welding (structural member) Assembly (static or Dynamic) Detailing & Drafting Animation (motion) Stress On centration

7. View Orientation :- Frount Top Side view Right view Isometric Perspective O rthogonal

8. THE SOLIDWORKS MODEL

9. The SolidWorks model is made up of : Parts - 2D design (Sketch), 3D design (Features) , Part design consider in the part design section . Assemblies - Assembling of two or more than two parts consider in this section Drawings - Designing with standards is consider in the drawing section .

12. Contour turning – the tool follows a contour that is other than straight, thus creating a contoured form in the turned part. Machining operations can be performed on CNC Taper turning – the tool is fed at an angle, thus creating a tapered cylinder or conical shape. Chamfering – the cutting edge of the tool is used to cut an angle on the corner of the cylinder, forming a “chamfer.”

13. Facing – the tool is fed radially into the rotating work piece starting from the outside or the inside diameter on one end, to create a flat surface on the face of the work piece. Form turning – the tool has a shape that is imparted to the work by plunging the tool radially into the work). Boring – a single-point tool is fed linearly, parallel to the axis of rotation, on the inside diameter of an existing hole in the part.

14. Drilling – it can be performed on a lathe by feeding the drill into the rotating work along its axis. Reaming can be performed in a similar way. Grooving/Cut-off – the tool is fed radially into the rotating work at a location along its length to either groove or to cut off the end of the part. Cut-off operation is sometimes referred to as parting Threading – a pointed tool is fed linearly across the outside surface of the rotating work part in a direction parallel to the axis of rotation at a large effective feed rate, thus creating threads in the cylinder.

15. Knurling – this is not a machining operation because it does not involve cutting of material. Instead, it is a metal forming operation used to produce a regular cross-hatched pattern in the work surface. CUTTING TOOL Fig 3.2 : Different cutting tools

16. Fig 3.4 : Left Handed Cutting Tool Opposite to the right handed cutting tool, a left handed cutting tool can remove material while moving rightward (here also take only top view keeping rake surface visible). Right handed cutting tool A right handed cutting tool, the common one, can remove material while moving leftward (take only top view keeping rake surface at top).

19. Various materials used in CNC machining and their properties . The best material for a particular project will depend on a number of factors, such as the desired properties of the finished product, the complexity of the design, and the cost. Material should have following Properties such as : High strength Good machinability Excellent weld ability Good hardenability E.g. 16MnCr5 Component : Gears
Shafts
Crankshafts
Bearing races
Bushings
Other components that require a hard, wear-resistant surface and a tough core SCM420H Components : Gears
Shafts
High-pressure pipes
Fasteners (nuts, bolts, screws)
Axles
Pins
Knives
Gun barrels
Valves
Flanges

20. G-Code Programming The language of manufacturing : G-code is a programming language specifically designed for Computer Numerical Control (CNC) machines. It’s the core way in which you give instructions to these powerful machines that cut, shape, and form materials with incredible precision. Concept of G-code and its role in controlling CNC machines Geometry in motion: The “G” in G-code stands for “ geometric .” This reflects the fact that G-code commands essentially dictate the movement of machine tools along various paths and speeds to achieve the desired shape of the final product. How G-code Works Design : The process usually begins with a CAD (Computer-Aided Design) model of the object you want to create. Translation : CAM (Computer-Aided Manufacturing) software translates the CAD model into a series of G-code commands. Instructions for the Machine: G-code files contain lines of code that instruct the machine on: Movement : Where to move its tools along the X, Y, and Z axes. Speed : How quickly to move the tools. Tool selection: Which tools to use and when. Spindle speed : How fast the cutting tool should spin. Coolant : When to turn coolant systems on or off.

21. Common G-code Commands Here are some examples of the types of commands you might find in G-code: G00/G01 : Rapid movement (G00) vs. Linear interpolation (G01) for tool positioning. G20/G21 : Switch between inches (G20) and millimetres (G21) as the units of measurement. G90/G91 : Specify absolute (G90) or relative (G91) coordinate positioning. M03/M05 : Turn the spindle on (M03) or off (M05). F: Set the feed rate (how fast the tool moves).

22. Maintenance Daily Maintenance Check lubrication levels Check levels of hydraulic system Empty chip hopper Check coolant concentration and fill levels
