Rules for Creating Machine Assembly to be Used for Machine Simulation
When creating a machine assembly to be used for machine simulation, you must follow the rules below:
To enable motion kinematics, the components of the machine assembly should be connected to each other only using sliders and pins. That is, the relative motions between the components should be defined. Optionally, you can specify the limits for the slider and pin motions.
You must define the absolute origin of the machine assembly using a coordinate system named MACH_ZERO. This coordinate system is used to assemble the manufacturing model. You must define this coordinate system at the assembly level and not within a component of the assembly.
You can access a library of basic machine assemblies by searching the PTC Knowledge Database with the keyword Machine Kinematics from the Creo Complete Machining Central Page at www.ptc.com.
