CAM toolpath is a sequence of tool positions and movements that a CNC machine follows to manufacture a part. It is created using CAM software, which takes a 3D CAD model of the part and generates the toolpath based on the desired manufacturing process, tool selection, and cutting parameters.
The CAM toolpath specifies the precise movements of the cutting tool and the order in which it will cut the material. This includes the cutting speed, depth, and direction, as well as any necessary tool changes, coolant applications, or other operations.

CAM toolpath generation is a crucial step in the CNC machining process, as it determines the accuracy, efficiency, and quality of the final part. It also affects the tool life and the overall machining time. Therefore, the CAM toolpath must be optimized to ensure that the part is produced correctly, efficiently, and with minimal tool wear.
CAM software typically provides various toolpath strategies, such as contouring, pocketing, drilling, and profiling, to match the requirements of different part geometries and materials. Users can also customize the toolpath by adjusting the cutting parameters, tool selection, and other variables to achieve the desired results.
Tool path associativity

One of the most important features of CAM is associativity. Associativity is the link between the part and the toolpath. When the part changes shape or moves, the associated toolpaths adapt and change as well. If there is a design change with the part, associativity makes it so the toolpaths just need to be recalculated, as opposed to completely reprogrammed.
Summary
In summary, CAM toolpath is a sequence of tool movements that a CNC machine follows to produce a part. It is created using CAM software and optimized for the desired manufacturing process, tool selection, and cutting parameters.
