iMachining: The CAM that reduces until 70% the time of mechanised

20 years putting in value contrive

Founded in 1998, CimWorks is formed by professionals with more than 25 years of experience in the area of the Technical IT. Ricardo Aguirreche, director of Development of Business of the Group CimWorks, went the attendant to present his company to the assistants to the seminar, formed mostly by engineers and industrial designers. Also it was present Esteve Galindo, general director of this company that from 2001 belongs to the Group CDM, with base in Parma (Italy). After these years of experience in the industry of the CAD, CAM, FALLS, PLM, CimWoks has more than 1.000 customers. Aguirreche Boasted that “16 years afterwards, our first 50 customers today still keep on being it”.

CimWorks Was the first distributor of SolidWorks in Spain and with this experience provides from 10 years ago all the products and services of SolidWorks, the software of reference in the market for mechanical design 3D. “We have the best team and the best means to realise learning, quality consultancy, technical assistance and other services required by our customers”.

Aguirreche desgranó The four areas of business of CimWorks that cover of integral form the different appearances of the strategy PLM of his customers: Technological Quality consultancy; solutions of creation of the Information of Product; solutions of Gestión of the Innovation and the Development of Products; and Professional Services.

SolidCAM Is the solution of CAM for SolidWorks, totally integrated cheese cheese, that covers all the applications CNC —milling 2.5D, mechanised of surfaces of high speed (HSS), mechanised of high speed (HSM), mechanised indexado multicara (4/5 axles), milling 5 simultaneous axles, turning, milling-turning until 7 axles, cutting by thread— and bears all the applications CNC of software of CAM, including 2.5D Strawberry, 3D Strawberry/HSM, Indexado and Strawberry 4/5 simultaneous axles, Lathe, Strawberry-Lathe for machines CNC multitorreta and multihusillo and WireEDM (Thread).

This revolutionary technology iMachining of SolidCAM allows to save until 70% of the time of mechanised CNC and prolongs the life the tools between 2 and 3 times. Juan José Jiménez, responsible of Applications of CimWorks, llevar the presentation of iMachining, application that carries in the miscellaneous sector years, with more than 16.000 places installed all over the world, but without presence in the Spanish market.

A lot of professionals of the mechanised have had difficulties in the processes of mechanised of high speed with his programs CAM because of the very little attention (or any) to the need of the user to obtain help in the decision on the conditions of suitable cut or to the dependency of the parameters of conditions of cut in the state of the machine-tool. These programs neither encouraged ‘' in treating of maximizar the area of cut by paths in espiral, and the reduction of the zone of cut by means of paths trocoidales or did not loan him attention to the vibrations and noises, and the possible forms to reduce them.

To give answer to these setbacks that posed , SolidCAM decided in 2006 develop the first product that really satisfied the expectations of the mechanised of high speed and provided an optimum solution to these problems. Like this it was cream iMachining, that with the peculiarity to having been designed of zero, without splitting of any previous program, generates automatically the programs of CNC that adheres to the principles of the mechanised of high speed, what allows a time of mechanised much shorter, life of tool longer and significant reduction in the wear of the machine-tool in comparison with the conventional methods of milling and with the systems of CAM existent.

Juan José Jiménez resumió the main aims of iMachining in four points: “experience simplified”, with a handle very simple by part of user; generation of paths optimised; efficient cutting of the piece; and high taxles of start of material.

An additional profit very important of the use of iMachining is the big reduction of the mechanical and thermal sensors tensions suffered by the piece in comparison with the milling conventional. This attains thanks to the only characteristic of iMachining that guarantees the conditions of exact cutting for each point of the path of the tool, and thanks to the success of iMachining to attain the highest percentage in the industry of zones of cut with paths in espiral. These profits are of big importance for a big number of industries, including the aerospace and the one of the mould.

This CAM includes two options: on the one hand, generator of independent paths, and by another a generator of conditions of cut, “and is here where iMachining differentiates of the others CAM of the market, that forget of this factor, since it is the user the one who has to give the conditions of cut, depth of past, speed, etc.”, affirmed Jiménez.

Regarding the paths, posed three difficulties in the most conventional systems: it overloads it in the tools, with loads impredecibles; cuttings in empty ineficientes; and paths no tangentes, with acute changes in the same. Instead, iMachining provides solutions to all these problems: the solapamiento between the past is controlled, by what does not overload the tool; it provides the mechanised exact of the tocho, by what no short in empty; and it offers paths tangentes soft with a mechanised also soft.

There are two factors that differentiate the paths of iMachining with the ones of other programs CAM: the use on the one hand of ‘espirales Morphing'; and by the another of ‘intelligent separation'.

The espirales Morphing are more efficient because they cause less retracciones, the tool remains in contact with the material and the machine advances faster but with soft movements. Instead, the paths of solapamiento parallel increase the replacements, the hits of tool and of machine, the entrances and exits and the retracciones. Unlike espirales conventional adapt of continuous form to the geometry of the element that is mechanising, maximizando the time of ‘tool cutting'.

By his part, the intelligent separation of areas, “that generates zones to be able to them mechanise later” forming espirales Morphing in any geometry and mechanising the zones with first material elder for like this save time of programming.

All the paths of iMachining cut material, and never ‘cut air'. From the initial approximation until the last cutting, there is a representation of the remaining block that updates continuously and ensures that each short path really material. The system applies a ‘Reposicionamiento intelligent', to depth of cut, to move the tool of a cut to the following, and only raises when it is absolutely necessary.

The program also provides control of the conditions of cut in each one of the points his path, thing that contributes more data in mechanisations of materials harder, for example.

“Up to now any software CAM calculated and provided the data of cut, was the operario the one who had to give the suitable values”, ensured Jiménez. It is necessary to take into account all the parameters, that are related between himself: advance, speed turn, depth, etc. The operario has to calculate in function of material to cut, tool… “Work of this form has his problems, because they do not take into account all the variables neither values neither are synchronised all the parameters, by what the results are not the most optimum neither those that allow to mechanise of form faster”.

With the ‘Technological Assistant' exclusive of SolidCAM iMachining calculates automatically the conditions of cut, taking into account all the parameters of mechanised in base to the tool, the geometry, the machine and the materials. In his database of material all these factors are synchronised, “by what the user does not have to define at all”.

This assistant is “the first in the industry”, and calculates advances, speeds, depths and width of cut optimised. It incorporates technologies like the called ‘Distance of past controlled' (slope of pantente) that ensures that the conditions of cut of the paths calculated with iMachining are totally correct, provides a load of constant tool and at the same time reduces the wear of the tool. Likewise, the control deslizante ‘iMachining Level Slider' allows that the user choose between 8 levels of adjust to adapt automatically to the hold ‘real', the tool holders, and the conditions of machine.
