1.计算机辅助设计(CAD)：
计算机辅助设计(CAD)是使用计算机设计物理产品模型的方法，这意味着计算机可用于帮助创建设计，修改设计和分析设计活动。计算机辅助设计也称为计算机辅助绘图。 CAD的目的是制作2D技术图纸和3D模型。因此，在简单中，我们可以说CAD在计算机上代表了您的零件几何形状。计算机辅助设计(CAD)软件通常由工程师使用。
CAD软件的示例包括AutoCAD，Autodesk Inventor，CATIA，Solid Works等。
Computer + Designed Software = CAD 2.计算机辅助制造(CAM)：
计算机辅助制造(CAM)是使用计算机软件来控制模块制造中的机床。 CAM将工程设计转变为最终产品。 CAM与传统制造不同，因为CAM在制造过程中实现了自动化。计算机辅助制造也称为计算机辅助建模或加工。 CAM的目的是使用3D模型设计加工过程。因此，在简单中我们可以说CAM将几何转换为机床。因此，没有计算机辅助设计(CAD)，计算机辅助制造(CAM)就没有意义。受过训练的机械师通常使用计算机辅助制造(CAM)软件。
CAM软件的示例包括Work NC，Siemens NX，Power MILL，SolidCAM等。
Manufacturing Tools + Computer = CAM CAD和CAM之间的区别：
| S.No. | CAD | CAM |
|---|---|---|
| 01. | CAD refers to Computer Aided Design. | CAM refers to Computer Aided Manufacturing. |
| 02. | CAD is the use of computers for designing means computers are used to aid in creating the design, modifying and analyzing the designing activities. | Computer Aided Manufacturing (CAM) is the use of computer software to control machine tools in the manufacturing of modules. CAM transforms engineering designs into end products. |
| 03. | Computer Aided Design is also known as Computer Aided Drafting. | Computer Aided Manufacturing is also known as Computer Aided Modeling. |
| 04. | The purpose of CAD is making 2D technical drawings and 3D models. | The purpose of CAM is using 3D models to design machining processes. |
| 05. | Due to CAD it is much easier, more accurate and faster drafting, making 3D models impossible without computers. | Due to CAM atomization in machining process is achieved. |
| 06. | So in Simple we can say CAD represents your part geometry to the computer. | So in Simple we can say CAM converts the geometry to machine tool. |
| 07. | For Computer Aided Design process only a computer and CAD software are required for a technician to create a design. | For Computer Aided Manufacturing computer and often a CAM software package along with that for manufacturing process requires a CAM machine. |
| 08. | Computer Aided Design (CAD) software is mostly used by an engineer. | Computer Aided Manufacturing (CAM) software is mostly used by a trained machinist. |
| 09. | Some examples of CAD software includes AutoCAD, Autodesk Inventor, CATIA, Solid Works. | Some examples of CAM software includes Work NC, Siemens NX, Power MILL, SolidCAM. |
