Richard Batchelor explains why we recommend that Tolcap can be applied to most plastic moulding materials listed in DIN 16901
by using the Tolcap map applicable to the same tolerance group.

Tolcap enables Designers to predict the process capability of parts even before prototype samples are produced.
Tolcap predicts Cpk - but what is Cpk, and is it the most appropriate process capability index to predict?

We are sometimes asked about geometric tolerances. While Tolcap gives sound estimates of process capability for straightforward tolerances,
this is because we have extensive series production data for the maps we publish. We don’t have such data for geometric tolerances such
as flatness, roundness, etc., so we won’t compromise the Tolcap data base by publishing maps for them...

In the current economic climate no manufacturer can afford substantial waste product and the costs associated with it. However, many companies have to deal
with scrap and re-work as a direct result of out of tolerance manufacture. In an ideal world, manufacturing engineers would have sufficient input in the early
stages of the design process to minimise such quality losses. Here Martin Raines, a director of Tolcap, explains how manufacturing engineers can help mitigate
the problem by applying the correct software tools...

As a design engineer, one doesn’t always have all the necessary experience of manufacturing materials, processes and treatments to
produce a design that will result in a product that requires minimal engineering change and will keep scrap and wastage to a minimum.
One of the ways this can be achieved is to provide the designer with the expertise of a manufacturing or machining professional.
Here, Martin Raines, of tolerance software provider Tolcap, suggest five ways that good communication and accurate tolerancing
can be applied to accurately predict, and thus improve, machinability...

Design and manufacturing departments co-exist in relative harmony in modern manufacturing. Gone are the days when engineering created
the design and manufacturing produced it and never the twain should meet. However, issues that do still divide the two include
engineering change, scrap and re-work. Here, Ken Swift of tolerance software provider Tolcap argues that more attention paid to
tolerances in the first instance would help businesses get it right first time more often...
