ACM – Adaptive Control & MonitoringAdaptive feed rate control and monitoring

siemens.com

ACM TechnologyThe adaptive feed rate control and feed rate monitoring is a technology based on the SINUMERIK machine tool system and is used in the machine tool sector to support digitali­zation in the production landscape.

ACM monitors the actual cutting conditions in realtime and automatically adapts the feed rate to achieve the optimum feed rate velocity.

When an overload condition is identified, ACM reduces the feed rate, and can output an alarm to stop the machine. ACM can also identify a broken tool, therefore avoiding any subsequent damage.

This realtime approach increases the productivity, extends the lifetimes of machines and tools – and ensures a reli ­ able and safe production process.

ACM functions • Realtime feed rate optimization • Protection when the tool enters the material • Protection against tool breakage as well as overload detection

• Detection of tool breakage and wear • Process monitoring • Process recording & visualization • Tool performance statistics

Product advantages

• Increased machine productivity by significantly reducing the cycle time

• Optimized tool lifetimes and increased tool utilization levels

• Higher part quality through constant load levels • Increased process reliability, offline NC program optimization, manual feed rate adaptation and visual tool inspection are not required

Two operating modesThe ACM system individually adapts the machining to your requirements and production targets. Depending on the specific application, two operating modes can be used:

• Adaptive feed rate control – ACM optimizes the pro­grammed feed rate. The stock removal process is acceler­ated if optimum cutting conditions exist – and is slowed down if workpiece geometry, material hardness and/or tool conditions demand it.

• Monitoring – tools, spindles and parts are permanently monitored for breakage, overload, missing tools, re peated machining runs on the same part and other deviations that occur in the machining process. As a consequence, ACM detects suboptimal states that can result in damage, therefore facilitating a timely inter vention.

ACM reporting & analyticsExperts at the shop floor level benefit from informative reports that ACM generates. From the recorded data, you can obtain information that will help you to improve and optimize ma­chining workflows. Reports on machine and tool utilization, actual feed rates, time savings, tool wear and tool life are avail able for every machine equipped with ACM.

Application areas for ACM software Your benefit in your production landscape

• Aerospace • Automotive industry • Power generation • Cutting tools • Mold building

• Regularly 10% – 30% shorter machining time

• Up to twice the tool life • Higher process reliability and safety across all workflows

Based on the requirement­optimized feed rate adaptation, ACM helps to reduce energy costs.

Can be used in almost all production technologies such as milling, turning, drilling and grinding.

Compatibility

The simple to install software solution is supported by the following CNC control systems: • SINUMERIK 840D Solution Line and Powerline • In conjunction with software and hardware, all other common control types are supported as well
