CNC & Machine Controls
Accuracy Gain From Linear Encoders
If the position of a machine tool’s axis is measured using a rotary encoder, then potentially the ballscrew is being asked to perform two contradictory functions. The ballscrew both drives the axis into position and indicates that position—because the ballscrew lies in between the encoder and the moving element of the machine. Control technology supplier Heidenhain calls this “semiclosed-loop” operation.
WatchUniform Control For All Product Lines
The Mitsubishi 700 series CNC is said to deliver advanced programming capabilities for high-precision machining and high productivity. All of the company’s product lines now incorporate this control, which is designed to allow greater compatibility between machines and to reduce the learning curve for machinists transitioning to new technologies. The unit is controlled on a 15" LCD touchscreen display.

Miceli Technologies offers the constant velocity controller (CVC), a CNC incorporating a new approach to toolpath algorithms that produces a processing speed of 50,000 blocks per second. According to the company, this enables fast, constant feed rates for machining complex geometries. In contrast, CNCs with lower block-read speeds might not be able to consistently push machines at programmed feed rates.

Bystronic offers CNC abrasive metering on all of its Byjet abrasive waterjet cutting systems. This system allows for the fine-tuning the amount of abrasive. On the fly, this amount can be changed from 0 to 1.
Read MoreProcess Systems Targeted For Smaller Applications
GE Fanuc Intelligent Platforms, a unit of GE Enterprise Solutions has released Proficy Process Systems in a 250-I/O size, single-computer offering targeted at smaller applications and OEMs. It is a fully integrated process control system that is said to improve quality, reliability, throughput, performance and efficiency. The process system allows users the freedom to architect and scale process control systems to best meet their needs.
Read MoreCNC For Five-Axis Machines
Designed for high-performance applications, the Fagor 8070 ETX CNC is based on an industrial-hardened Windows operating system running on an XP-embedded platform. A host of online software configurations can be integrated for a true open-architecture system. In addition, the control is built with a solid state disk for reliable operation in harsh industrial environments.
