Delcam CRISPIN to show latest footwear CADCAM at Shoe & Leather
Delcam CRISPIN will demonstrate its broad range of design and manufacturing software for the footwear industry at the Shoe & Leather exhibition to be held in Guangzhou, China, from 2nd to 4th June. The company is already the world’s largest supplier of CADCAM software to the footwear industry – it is the only supplier able to provide a complete solution for the design and manufacture of both uppers and soles. More recently, Delcam CRISPIN has extended its coverage with the addition of dedicated software for the development of orthotics.
The most significant new product for conventional footwear is TechPac – a 2D system to generate technical packages for footwear designers to supply to their manufacturing partners. TechPac allows designers to specify the manufacturing processes to be used and the sequences of operations to be followed at all stages of the production of the shoe. It will help ensure that the design is produced exactly as specified and to the required delivery schedule.
The system is supplied with pre-defined templates to specify the path for the flow of manufacturing data during production. These templates can be modified by the user to cover any specific requirements of the design and manufacturing companies, or of the particular project. 2D part geometry, models and images can be imported into the documentation from the range of Delcam CRISPIN design software.
The most important of the new updates is the latest release of the 3D upper design module, ShoeDesign. ShoeDesign provides a comprehensive range of options to develop new designs, either based on an existing last or when creating a completely novel product. The software comes with a wide range of materials, textures and colours, while features like stitching, padding, eyelets and laces can all be included to complete the design.
The main focus of the new version has been on improving the ease of use, so making the software simpler for new users to learn and faster for experienced operators to use. The interface has been revised, in particular to reduce the number of icons on the screen at any one time. In addition, the cursor action has been improved to speed up the drawing of style lines, and the selection of menus and icons.
The new version of the LastMaker software for last design has also been made easier to use, both for the creation of standard lasts and for the development of bespoke designs. Improved creation and editing tools for cross-sections have been added to allow more specific adjustment to the overall design. Similarly, profile-line editing has been enhanced to make it easier to modify the outline shape of the last. Templates are available for the toe, back-curve and bottom sections ofthe last, so that these sections can be incorporated into the design more quickly and easily.
Developments have also been made to the base 2D Engineer package. The main new functionality allows Edge Templates to be appended to a part boundary, allowing dependent margins, makers, stabs and notches to be added after theboundary has been created. In addition, work has continued on many areas of 2D Engineer to make the software faster and easier to use.
For orthotics design and manufacture, OrthoModel and OrthoMill provide a complete solution for the production of high-quality insoles for both the comfort and medical markets. The entire process is driven by a series of menus, which incorporate the terminology used by the industry to describe the various features of the orthotic. This makes it easy for medical and footwear professionals to use, even those having no previous CADCAM experience.
The latest addition to the program is a new method for creating “foot-positive” models. This allows patterns to be designed directly from scan data taken from the patient’s foot to create foot orthotics in a variety of materials, including carbon fibre.
A new “cast-dressing” option allows the user to apply corrections directly on the scan of a patient’s foot when designing orthotics. This process duplicates on the computer the modifications made to the cast by adding or subtracting plaster using the traditional methods. In a related development, the scan and the orthotic can now be overlaid and viewed together, so that the extent of the changes can be seen easily.
