Shape Order Input


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.  


Sample Scale Drawings of a Miss Shapen Rectangle

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 Compatibility


• Speed and Accuracy of



• Value for Money


• 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.  






One more word of caution  


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 orders.
