Sorry, wrong meeting This mould is 1.0 Metres square
European research project -Cimatron E Micro Milling is the result of Cimatron’s participation in a micro-milling research project funded by the European Community and sponsored by the Fraunhofer Institute for Production Technology (IPT) in Aachen, Germany. -The forum brought together leading technology suppliers and mould makers to investigate and test processes for the manufacturing of high-precision injection moulds with complex 3-D structures and high surface quality. Various Mouldmakers
1. Definition of requirements 2. Machining process investigation 3. Milling machine development 4. Development of cutting tools 6. Verification of achieved results 5.

Accuracy improved by excellent Design-for-Manufacturing functionality (DI, Quicksplit, Hybrid modeling) Accuracy improved by use of advanced algorithms for machine program generation. For Finishing, Cimatron`s Specific strategies generate very good toolpath results Quality/Reliability can be improved by variety of “smooth” NC strategies, e.g. for rounding corners Results related to CAD/CAM
This Project for an existing customer Generate mould for False teeth, with minimum bench work, from digitized data
The CAD Tecnology: ReEnge + Geomagic allows to build the teeth's surfaces, previously digitized
Cimatron E Scanned data converted to surfaces and added to solid model for Cavity & Core
Cimatron E... so, now the mould is fully designed using CimatronE.
The NC-Benchmark requirements were: -Mill molds for artificial teeth maximizing surface quality with tolerance required of.0005. - Minimum bench work -Use of Ball tools Diameter 1.0 mm for Teeth Diameter 1.5 mm for other surfaces -After a selection of the most important Systems on the market. -“another” and Cimatron were chosen for the benchmark
The first attempt: to use E version. 6.0 and existing strategy's
Surface Quality, good for large tooling, unacceptable for small work
Customer decided Surface Quality was not good enough
The winning solution: New algorithms provided by Cimatron -Customer asked Cimatron for help because he needed a new a more powerful solution. -Cimatron used the new “MICRO MILLING Module” which is optimized for small parts. -We sent our customer the G-code program, produced inside Cimatron, to test -And results were…..
Design Change Design-for-Manufacturing Design a cavity with a minimum radius of 150µm Good Splitting
Design of Cavity »Micro Rotor« m o l d Challenge, to create mould parting faces that were adapted for micro machining we realised that tangency was of the greatest importance

Advantages for ukMIG Members Take advantage of work already done in this arena. Work with a partner already accepted by European funding organisations. Have access to developers for new functionality. Write code specifically to test your applications with API’s (C++). Cimatron Uk is already working with a leading UK research university using FULL 5 axis on a micro milling project Synergy between existing members
A word from Cimatron CEO ”As a pioneer of micro-milling technology, Cimatron is in a unique position to introduce a new and exciting product to the market,” explains Danny Haran, President and CEO of Cimatron. “Our software solution – developed in collaboration with leading cutting tools and machine manufacturers – answers the increasing need to cost-effectively manufacture high precision miniature components in large quantities for such demanding industries as medical, cellular and optics manufacturing. This cutting edge technology will make our customers more competitive and successful in these fast growing markets.” -Cimatron’s solution meets and exceeds the requirements of micro-tooling: a unique algorithm and special machining strategies successfully apply Cimatron E’s proven CAD/CAM functionality to support milling at levels traditional NC software cannot achieve. Characteristics of the solution include: high precision, tight machining tolerance, effective handling of imperfect imported geometrical data, direct surface milling, and 3- & 5-axis toolpaths.
