Capabilities• Enhancing GMC in such a way that the user can
more easily describe a motion sequence andreapply it from a template without going into eachsub-operation for redefining input
• Framework for providing better OOTB coverage forcycle based probing
• Not limited to probing, can also be used for othermotion sequences like complex hole machining orspecialized milling that our current processors donot support
Customer Benefit• Create controller and company specific user-cycles
for specialized machining methods
Referenced GMC Framework

• A Reference sup-operation has beenadded to define key input
• When applied from a template the useronly has to satisfy the key input in orderto get the motion sequence executed

• GMC is the first operation type that allows theusage of expressions in move definitions, loops& conditionals
• For every input defined, the system creates anexpression that can be used when constructingthe motion sequence
• Every input field of a sub-operation nowprovides and option to describe a functioninstead of a fixed value
Expressions

• If a tool is defined for a Referenced GMC operation, forevery tool parameter the system automatically createsexpressions that can also be used when constructingformulas
