DELMIA MACHINING
THE CHALLENGES
It is extremely important for every  manufacturing company to guarantee the quality and to keep the agreed lead times for the manufactured products. An important prerequisite for this is the optimal organization of the internal business processes, effective planning and the availability of modern machinery in the enterprise. In the same time it is of great importancethe use of modern software systems to leverage the level of digitalization of the Research  and Development and of the processes in the manufacturing.
Modern systems for manufacturing planning and CNC programmings are entering the enterprises today. This allows the simulation of the manufacturing technology  and their easier programming. Today, computer simulations of the technological process make it possible to simulate, predict and evaluate possible technological strategies, to select the most optimal of them and to achieve the highest quality at the lowest cost. One of the leading solutions for the simulation and programming of CNC machines is DELMIA 3DEXPERIENCE Machining.
CHARACTERISTICS
DELMIA 3DEXPERIENCE Machining is a CAM software used for the simulation and generation of NC programs for CNC machines. It is part of the business platform 3DEXPERIENCE and has full integration with the the CAD system CATIA. The architecture of DELMIA 3DEXPERIENCE Machining has  following features:
1. The designer and the technologist shall use an unified working environment for three-dimensional design, strength and kinematic analysis and generation of control programs. This allows you to easily update the processing programs when changing the geometry of the product.
2. DELMIA 3DEXPERIENCE Machining is end-to-end solution for the planning of manufacturing operations- from the programming of processing strategies, through the tools used to the necessary technological equipment. Moreover, DELMIA 3DEXPERIENCE Machining allows the simulation of the work not only of the cutting tools, but also of the whole machine. This is possible by uniform presentation of the geometric information of the processed product, the technological equipment for its fastening, the technological map of the processing operations and the necessary cutting tools.
3. DELMIA 3DEXPERIENCE Machining has a completely new interface enabling technologists to work efficiently and easily with the system. It is easy to use for young engineers and the working methodologies are adapted to the qualification programs of universities and technical high schools.
WORKING PROCESS IN DELMIA 3DEXPERIENCE Machining
Each project in DELMIA 3DEXPERIENCE Machining follows an systematic approach to generate the NC program. The work methods set out in DELMIA 3DEXPERIENCE Machining have been optimized over the years based on the experience of tens of thousands of successful projects developed by machining technologists around the world. Dassault Systemes' software engineers use this experience and continuously improve the system, adapting it to new work strategies, types of materials and innovative processing tools, taking into account the latest scientific discoveries in the field.
The main steps of work in DELMIA 3DEXPERIENCE Machining are the following:
1. Import of the 3D model
After importing the 3D model of the processed product, it is corrected if necessary (in case a CAD system other than CATIA is used).
2. Setting the fixation and machined areas of the workpiece
The next step is to set the base of the product and select the machined areas of the model.
3. Choice of technological process
The selection of the technological process of processing follows as a s next step. DELMIA 3DEXPERIENCE Machining provides guidelines for selecting the most optimal work strategies based on the world's best practices, but the technologist can change and adapt the technology at any time according to his specific needs. After choosing the strategy, the technological sequence can be changed by the technologist.
4. Performing initial simulation
In the next step the simulation of the work of the cutting tool, the way of work, the withdrawal of work is carried out and depending on the needs a simulation of the work of the whole metal-cutting machine can be carried out taking into account its kinematics (typical for 5-axis machining). Through the various possibilities for visualization of the machining process at each stage it is possible to trace which machining tool from the store works, to determine the amount of material taken, the depth of cut in a given operation, the wall thickness of the part after a given operation or to identify possible collisions. The simulation takes into account the actual spatial location of the part, the gripping devices, the machining tool and the machining head, as well as the overall dimensions of the machine table. When a collision is detected between the machining tool, the spindle, the workpiece and the machine, the simulation can be stopped.
5. Optimization of the technological sequence
The technologist can set a new machining trajectory, change the machining approach from 3- to 5-axis milling. The metal-cutting machine is simulated not only by its geometric shape and kinematic capabilities, but also by the permissible feed limits. For example, in case the submission limits are exceeded, this is reported by the program.
6. Output of the final NC program and project documentation
The last step is the output of the control program and its documentation.
