The expertise and professional competence of Fidia Service Dept. integrated in the supply ensure the investment’s validity in time.
Advanced technology and features
Fidia controls have always been appreciated for their high level performance and for the comprehensive range of features supplied as standard. The architecture of Fidia NCs, with two separate processors, takes full advantage of the power of the dedicated CPU for axis and PLC management, based on a RISC Power PC. The PC section manages the operator interface: in this way, any programming or display task, even an onerous one, can be performed without interfering with the machining in progress.
Numerical controls C20 include an industrial PC, complete with:
- Intel Core i3
- 4 GB RAM memory
- 500 GB hard disk
- N-vidia graphic board integrated
- 2 Ethernet interface to 1 Gbit/s
- Windows® 7 – 32 bit
- Flash drive 32 GB for back-up
- 8 USB ports J RS232 serial interface
- Audio inputs/outputs
The operator panel comprises:
- 19” TFT monitor
- extended 101 key keyboard
- 16 softkey for management of the operator interface
- integrated industrial mouse (an external mouse can be applied)
- pushbutton panel for machine functions with handwheel, 2 potentiometers, 2 pushbutton keys, emergency pushbutton and various custom buttons
From its first installation on a PC base in 1995, the Fidia NC has been open to all applications in the Windows® environment. Over the years, software for all types of requirements has been installed on Fidia NCs:
- measurement and testing
- monitoring and display
Applications integrated with the numerical control can also be developed owing to the standard CORBA interface that makes the Fidia NC open to the most widely used operating systems and programming languages. Through the CORBA developing kit and its interface licence is possible to read, by TCP-IP, NC parameters and PLC registers.
The Fidia C20 high end control can be equipped with a 19“ LCD TFT display. Apart from the Fidia software applications, it also supports other software products, such as Viewer CAM systems or measuring software that may run in parallel. The IPC – CNC rack comes up with state of the art PC hardware and a Microsoft operating system. The C20 pushbutton can also have an additional 9 buttons kit for a better customisation of the machine functions.
In order to enable control from two areas for machines with long axis travel, a second operating panel with LCD TFT display and keyboard can be connected. The C20 fulfills highest demands for complex applications where 5-axis HSC machining with RTCP and a large number of drives (Gantry, Tandem, multiple axes) must be managed simultaneously.
The C20 manages complex upper Gantry machines with 12-14 motors for 5 axes as well as heavy portaltype machines with different exchangeable head systems and spindles. It is possible to manage up to 32 digital drives with linear motors, torque motors or conventional motors. The C20 is therefore the right choice for all complex machines.
Software and hardware updates
The numerical control structure allows for simple and fast updating of NC software as well as ISOGRAPH and HI-MILL applications. The NC architecture with its double processor also allows for hardware upgrades by replacing all or part of the PC (memory, hard disk, network boards) without modifying the other components. In this way, the control can always be kept up to date by implementing both hardware and software innovations as they become available.
Menu and softkeys
The graphics environment is intuitive and easy to use, while the set up of operations on the numerical control is further facilitated by the use of softkeys. Switching between different operating environments (CNC, ISOGRAPH, HI-MILL) allows the user to perform simultaneous tasks with complete safety.
On line Help / Log file
All functions available on the numerical control, whether standard or optional, can be rapidly consulted by means of the on line Help. The log file records all events (messages, commands, etc.) sequentially to facilitate diagnostics, including remote diagnostics via Teleservice.
Graphics – 3D files visualization
Simulation of machining programs and graphic visualization of tool path both before and during the machining. An optimized and even simultaneous visualisation for displaying large and different format files enables a quick check of the milling path.
Its main features as follows:
- visualization of the mathematical model laid upon the tool path;
- display of multiple paths marked with different colours;
- vertex coordinates measurements, distance between two points and angle formed by two segments for each loaded tool path;
- management of ISO-DXF/DWG-IGES-STL-VDA-FS-PRJ (HI-MILL project) formats.
Parameters and procedures
Although the technical department usually checks all CAM programs, for several reasons (machine change, unexpected overall dimensions, change of the origins) the milling path could not be suitable for the machining. In such cases the tool path should be newly calculated, partially or in full, or the file should be modified (movement release clearance, shift of origins, axis switch, etc.). On Fidia controls instead, the operator can directly activate all these variations (roto-translation, scale factors, axis change, etc.) to the aid of suitable parameters but with no need to perform corrective actions on the part program. In addition to this, where changes are to be applied with a specific sequence on file parts or on several files, the programming through Procedures is provided allowing for an easy and maximum automation of part program sequences thus resulting in maximum efficiency.
In any kind of 3 or 5 axis machining, with continuous or indexed heads, when there is an unexpected breakdown there must be a quick and simple intervention. Included in the Fidia NC are special functions that make easier for the operator doing the following procedures:
- automatic re-positioning of the tool on the part, with 3 and 5 axes, following manual retraction using the “Retract” function
- translation of the tool along its axis during machining by means of the electronic handwheel (virtual quill)
- fast and flexible cycle resume with optional re-execution of graphics and the ability to re-position one axis at a time
Extended Tool Table
It enables to define up to 10000 tools identifiable with a 16 alphanumerical name that can be called from the part-program. The table can be customized by inserting fields handled by the PLC and can be exported according to the Windows® standard formats. Also the visualization can be customized by choosing the columns and by defining the sort order of rows. The tool table completion can be performed directly on the machine or it can be done externally and then transmitted to the NC via the network or via the USB port. The combination with the tool identification systems results particularly useful within a tool centralized management.
To avoid time-wasting operations on the machine it may be useful to use the FIDIA piece alignment features. To this purpose some specific dialog pages with graphic support can guide the operator in calculating and activating the suitable rotations. The alignment cycles can be performed with digital probes or more simply with a tool: in the latter case the points have to be collected manually. Several cycles are provided referring to the geometrical elements available on the piece: working surface, holes, pins. On machines with swivelling head, rotation for piece alignment may also be applied to rotary axes, so that even in 5-axis paths the tool will keep the proper orientation in relation to the piece.
