Very sophisticated mathematics has been developed in Trimloss to allow the quickest
and simplest method of inputting all the required geometry for a range of completely
different shapes. The input operator often has a choice of different input shapes,
so the easiest in any one instance can be chosen, making this software both very
comprehensive and easy to use. This makes life a lot simpler for glass shops with
toughening plants, whose customer’s often have many different methods of shape definition.
These shapes not only allow the input of the geometry of the large leaf of each
unit, but also automatically calculate the geometry of their pairs with stepped edges
in any combination. The shape mathematics, then uses extremely complicated but fully
working algorithms to calculate the required shaped spacer bar geometry for whatever
spacer inset dimension has been specified. These algorithms work completely independently
of the original shape mathematics, so they will work even when another CAD system
has done the original calculations and the end results keyed into UPS using our equivalent
of DXF input. As far as we know, NO OTHER SOFTWARE CAN DO THIS. Our equivalent
of DXF input can also be used accurately to input the geometry of templates, thus
avoiding the inconvenience and expense of sending them to a toughened glass supplier.
Even rival software suppliers using sophisticated and expensive CAD packages, requiring
highly qualified operatives, cannot match all these capabilities.
Once each shape has been entered, UPS checks for anything that can possibly be wrong
with the input. Some shapes have redundant information, enabling a cross check to
be carried out to make sure that every part of the input is compatible. With each
shape, there is the option to enter extra trim dimensions on any of the four edges
bounding the shape. This is so that when the initial rectangular cuts are broken
out, they cannot veer off onto a shape cut which should not be touching. In some
cases, the trim cut is unnecessary like on the bottom of a raked head shape. In
other cases, UPS knows that the trim cut is optional like the two sides of a raked
head. In the final case, UPS knows that the trim cut is mandatory, like the top
trim on a raked head.
There are other cases where further checks can be performed. For instance, UPS knows
that it is impossible for the lengths of the two shorter edges of a triangle to add
up to less than the length of the longest edge of the triangle.
It may seem highly implausible, but there are some rival shape order input systems
with none of these error checks, so that errors in the shape data are detected only
after the cutting table has started cutting the shape. This probably means that
the whole stock sheet has then to be scrapped, before trying to detect the source
of the error and then having another attempt with fingers crossed because another
error might still exist.
The Trimloss ability to calculate the detailed spacer bar geometry for shapes, to
give all the finished sizes, taking account of both spacer insets and any stepped
edges, means that even glass shops without toughening plants can use these results
to make very accurate spacer bar assemblies, prior to the ordered toughened glass
being delivered. This means that no leaf of glass needs to be used as a template
to work out the required spacer bar geometry. On units with stepped edges, this
is going to be the Low E leaf, which would therefore otherwise be prone to damage.
As far as we know, NO OTHER SOFTWARE CAN DO THIS.
We have a wealth of experience in glass cutting, glass edge deletion and spacer bar
preparation. This is especially important for shape units. When buying new equipment,
do not make any decisions until you have taken our advice concerning:

• Equipment Reliability
• Quality of Vendor
Three drawings comprised of the larger outer leaf, any smaller leaf with any combination
of stepped edges and the spacer bar geometry, can all appear drawn to scale with
detailed dimensions on the computer screen and/or the printer. These drawings with
accurate co-ordinates for DXF input, can also appear on orders going to the toughened
glass supplier, thus eliminating the need and possible extra cost of sending templates.
In school life, it is obvious which pupils have mathematical ability and which don’t.
Every pupil in high school is going to be comfortable with basic arithmetic, but
only about a third of pupils are comfortable with even basic mathematics, a lack
of which being a failing which can never be overcome.
To appreciate all the shape features in UPS/Trimloss, the manager of a company needs
to be able to do basic mathematics so that he isn’t frightened by technical drawings,
but also, the UPS shape input operator needs this ability too. We know when this
ability is lacking in operators, when we are telephoned every time they need to input
shape orders. We also know when this lack of ability extends to the management,
because we then see little use of our shape features, often leading to them losing
