Gentlemen,
Given:
5 different machines with EMC controls - 3 each 5 axis and 2 each 3 axis
4 different machine configurations - each of the 5 axis mills
are a different configuration
the
2 three axis mills are the same configuration
5 sets of tools in tool changers - no master tool list in the shop
2 nc programs - one 5 axis program and one 3 axis program
each machines motion limits will allow all the machines to run
the 3 axis programs
each of the 5 axis machines motion limits will allow each of
the 5 axis machines to run the 5 axis program
Proposed abstractions:
tool list abstraction - A given tool (ie: nc spot drill) has a
small chance to be in the too1 1 position on 3 of the 5 mills.
A lot of time is spent
changing the program's tool numbers to match what is in the machine.
A percentage of scrap is
caused by improper editing.
A table to match tool
numbers in the program with tool numbers in the machine would allow
the editing of only the table. The matching function could be tool
numbers but could also be tool description or some other feature.
axis abstraction - some 5 axis mills have AB rotary axes
some 5 axis mills have AC rotary axes
some 5 axis mills have BC rotary axes
to run a program with BC axis
commands on a mill with AB rotary axes a substitution will have to be
made.
a table in the control to allow
this substitution without changing the program would eliminate an
error source because any time a program is edited an error can be
introduced.
thoughts?
thanks
Stuart
