Our experience in Metal Machining

Key CNC features

• PC-based solution: a single hardware hosting CNC together with HMI and CAM, with completely separated and independent resources, to increase reliability, simplify output of real-world programs and cut cost
• Look ahead up to 256 blocks, more than 15.000 instructions/second
• Multi-channel architecture that can run several part-programs at same time and synchronize them
• Standard ISO6983 syntax for full machining definition and parametric nested programming, that simplify interface with third parts CAD-CAM
• Up to 96 controlled axes, part of them dedicated to machining, remaining for part moving and clamps
• Gantry axes
• Motion control typical features available in CNC: gearing in position, electronic cams
• Jerk-controlled movements of all axes involved in movement and separately of the tool tip, to prevent mechanical stress and reach the best finishing surface
• Automatic adjustment of spindle rotation speed according to programming, to keep speed constant or keep removed material quantity constant, during turning machining
• Filleting on turning
• Tapping on milling
• High speed machining to smooth corners while keeping a defined tolerance, to reduce mechanic vibration, cut machining time and improve finishing results
• Superfinishing machining algorithms
• Volumetric compensation of positioning inaccuracies due to mechanical asymmetries and machine misalignments
• Vibration suppression algorithms to prevent part damages, extend machine lifetime and increase machining quality
• Coordinates and working origins roto-translation and mirroring
• High speed machining available on 5 axes interpolation
• Programming tool tip position and orientation with Tool Centre Point (TCP) applied to bi-rotative heads, tilting tables and turn-mill 5 axes configurations
• TCP parameter auto tuning cycles available. Newly found parameters can correct CAM generated part-programs to match with reality
• Support of many different servo digital interfaces control of servos with position or velocity reference
• Velocity feed forward and torque feed forward to have trajectory following error close to 0
• OPC UA server to connect with MES
• Remote I/Os connected with EtherCAT fieldbus thousands of I/O signals can be exchanged
• IO-Link interface gateway
• Integrated safety with FSoE

HMI

• Easy integration of OEM HMI using reusable user controls or customization of the ISAC provided interface
• High definition, interactive machining preview that operator can rotate, pan or zoom. Path already cut is identified using different colors to quickly understand the amount of work done
• Simulation environment available to check mechanical constraints and collision before running the part-program, evaluate machining time and optimize working cycles

Tooling

• Tool life management
• Tool preset, online wear measurement and integrity check
• High efficient, automatic Tool change management
• Lathe tool size compensation on virtual tool tip, or radius compensation
• Advanced milling tool radius compensation using big geometrical look ahead to prevent part damages
• Fast automatic tool change with linear, rotating and tray tool warehouse
• Random tool change with tool families management

Working aids

• Resume of machining after unexpected shutdown from last executed block or from any graphically selected block. Works with repetitions and nested macros
• Support of suspension of machining, manual check and maintenance and resume from position in trajectory
• After resume, variation in tool length automatically compensated
• Safe tool retract from material on arbitrary tool current direction
• Robotic module
• CNC can control robot kinematics such as DELTA, SCARA, PUMA
• OEM can create additional robot kinematics
• Robot piece pick up, loading and unloading trajectory can be controlled by same CAM that appropriately knows the geometry of the stock and finished piece

PLC logic environment

• Powerful PLC logic shell compliant with IEC61131 standard
• Extensive application libraries
