Rules for Creating a 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 name the components of the machine assembly as follows:
◦ 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.
◦ Define the spindle loading position of the machine assembly using a coordinate system named TOOL_POINT.
◦ Any solid tool model used in the manufacturing model should contain a coordinate system named TOOL_POINT. This coordinate system is used to assemble the solid tool model on the machine assembly.

You must define the MACH_ZERO and TOOL_POINT coordinate systems at the assembly level and not within a component of the assembly.

Library of Basic Machine Assemblies
A library of basic machine assemblies to show machine kinematics with NC is available from PTC Support.
