OpenCNC - MDSI - #1

MIAI J ...toTefal Manufacturing Solution^

OpenCNC® software is a production-proven, unbundled, software CNC that has logged millions of hours since 1993. Unlike traditional CNC controls, OpenCNC® software requires no proprietary hardware or motion control cards. Combining a soft CNC, soft PLC and HMI in one application, OpenCNC's open, modular, all-software architecture provides robust CNC control, connectivity to MAXIMUM Factory and easy integration of third-party software. MDSI customers have increased productivity, streamlined manufacturing processes, reduced machine tool control costs, and extended the productive life of their machine tools.

OpenCNC provides high-speed machining through its innovative software architecture that combines multi-axis interpolation and servo update in one process. This process, invented by MDSI, is unique in the control industry and results in higher cutting speeds and higher-quality surface finishes:

CNC block processing: 1,500 blocks/second or 670 Msec/block

Axis interpolation/servo update rate: 500 Msec

Part program size: 4 gigabytes (limited only by available memory in PC)

Max. spindle speed: Practically unlimited (limited only by hardware)

Max. feedrate: Practically unlimited (limited only by hardware)

Interpolation and servo update combined in same process increases efficiency, increases speed and improves part quality.

Bottlenecks eliminated. By handling motion entirely in software, OpenCNC eliminates the lag times that occur when messaging to a hard motion card. This improves efficiency and performance, espe­cially in 5-axis aerospace machining and other critical, close-tolerance high-speed applications.

Adaptive Look-Ahead dynamically adapts acceleration and decelera­tion rates based on part program tolerance requirements and ma­chine dynamics.

Blocks are not skipped at high speeds. Many CNCs skip program blocks to maintain speeds, which diminishes part quality. OpenCNC does not skip blocks at high speeds.

FEATURES

Common control technology across a full range of machine tools: single- and dual-turret lathes, single-and multi-spindle precision drills, routers, mills, grind­ers, gear hobs, dial index machines, and gantry machines

Servo loops closed entirely in software running on a standard PC with a single processor and a single op­erating system. No proprietary hardware. No motion control cards.
