Learn about G-code how CAM affects your tolerances.
- [Instructor] CAD designs represent…the ideal geometry of a part.…When that part is manufactured,…the reality of machine physics…and material properties will impact…how closely the manufactured part matches the CAD design.…Computer-aided machining software…or CAM software translates the CAD design…into instructions that can be sent to a CNC machine tool…to control how that machine tool fabricates a part.…These instructions correspond to a list…of movements that the machine will be commanded to make.…Although the surface of a physical object…may form continuous lines and curves,…the tool paths generated by CAM software…are made up of a collection of points…that the machine will move through.…
The more points used in a tool path,…the smoother the profile of the movement will be…but the slower the machine will move.…This represents a trade-off…between speed and precision.…Since the tool path and machine control instructions…generated by the CAM software…may not incorporate information about expected tolerances…of the part to be manufactured,…
