Automatic Compensation Capabilities

ActiveEdge tooling can be integrated with a gauging or probing device, allowing CNC programs to monitor bore sizes and adjust accordingly as part of a closed loop manufacturing process.

  1. Initial Bore — A hole is bored using the ActiveEdge tool.
  2. Measurement — The bore is measured using a probing or gauging system, the measured diameter is then translated and saved in a variable in the CNC machine.
  3. Assessment — This measured diameter is assessed against a set of Statistical Process Control (SPC) macros that run on CNC machines, setting an upper and lower control limit on bore sizes.
  4. Compensation — If bore sizes are not within this user defined parameter, an automatic compensation request is sent directly to the ActiveEdge tool, which adjusts to ensure the next machined bore is returned to nominal size.

Remote Adjustment — Micron accuracy at the touch of a button

The ActiveEdge remote allows simplicity in adjustment, critical diameter changes can be made to the tool's cutting edge at the push of a button.

Simply entering the tools unique ID and the required diameter change into the remote controlled Adjuster initiates a compensation through wireless transmission.

Up to 7 independently adjustable ActiveEdge cartridges can be integrated on one bar, machining multiple critical diameters at the same pass.

Improve Manufacturing Quality

ActiveEdge ensures a superior quality when machining components, regardless of the workpiece material or bore specification.

Automation of bore sizes maintains a tight tolerance bore diameter, keeping bore sizes within a predetermined upper and lower control limit.

Organisations can achieve a superior process control, with a lower deviation on bore sizes and higher Cpk statistic.

Rigibore have worked with the following presetter companies to successfully integrate ActiveEdge hardware:

Reduced Operator Intervention

The ActiveEdge solution seeks to eliminate manual intervention from the tool sizing process, and so reduce the risk of errors. The automation of bore sizing provides a solution to the varying skill and experience levels found on the shop floor. It contributes significantly to a reduction in scrapped parts and rework rates.

This feature has proved extremely important in high value part production, as found in the aerospace industry, where a failure to meet critical tolerances on expensive components can lead to significant financial loss.

The ability of ActiveEdge to deliver micron accurate compensations automatically, removes the reliance on skilled operators to make manual adjustments. Employees are then released to take part in other vital shop floor activities.

Maximise Production Efficiency

ActiveEdge technology allows organisations to produce high quality, precision components on schedule.

Micron accurate changes can be made to a tool’s cutting edges while it is in the machine tool magazine or carousel. This significantly increases spindle utilization, by allowing other machining operations to take place in parallel with the compensation process.

Organisations can allow tool sizing operations to proceed without an operator being present, significantly increasing productivity with minimal cost implications. ActiveEdge tooling supports “lights-out manufacturing”.

FAQ

  • What is the adjustment range?

    0.3mm on radius - but we build the tools so that at nominal they are at 1/3 of their way through the adjustment range. This gives 0.2mm of positive movement on radius allowing for wear compensation.

  • What style of inserts are used?

    All our products take ISO standard inserts. ActiveEdge cartridges support TC..11 and CC..06 inserts.

  • How long do the batteries last?

    In normal use between two and three months, it depends how often you adjust the tool. A battery replacement guide can be found below.

  • How can I switch off the tool/save battery life?

    When a tool is not in active use, it should be switched off completely to save power and extend the battery life. The 'switch off' button (found in ActiveNet) sends a request to the interface to shut down the tool. The tool can be turned on again by pressing the pressure switch on the upper face of the yoke.

  • How accurate is the adjustment?

    The cartridge is calibrated to a tenth of a micron, this means that we can guarantee micron accuracy in compensation.

  • Is it affected by coolant?

    The system is designed and tested for use in high pressure coolant. The tool is rated IP68 and pressure tested twice during manufacture.

ActiveEdge Tool Breakdown

The tool can be made with any taper, spindle connection or adapter to suit the customer's machine requirements.

The tool is a custom-built special, designed using Rigibore's RADS software, and can be supplied in 3-4 weeks. Tools are engineered for the specific application, and typically balanced to G2.5 to ensure accuracy and rigidity in cut. Chamfer tools, semi-finishing cartridges and up to 4 finish bores can be completed with one tool.

The Yoke contains the batteries and radio hardware that allow the tool to be adjusted remotely. With ActiveEdge there is no required modification to the spindle or machine, this means that the tool can be adjusted in the carousel, at the presetter or if required, in the spindle.

Sealed with an 'O' ring the tool yoke is protected against coolant ingress.

The two 6v batteries power the radio communication and actuation of the mechanism in the cartridge.

Batteries last around 2-3 months of standard use in a production environment. System warnings are given when they need changing.

This user replaceable cartridge contains the drive mechanism, calibrated measurement device and adjusting slide, with the capability to move the cutting edge 1 micron on diameter.

ActiveEdge Cartridges supports Standard ISO Inserts CC..06, TC..11 and CP04 Inserts.

Upto 4 cartridges can be individually adjusted on one tool assembly.

The cartridge is capable of supporting through coolant up to 80 bar. Coolant is supplied through the cartridge directly to the cutting edge of the insert.

The pretensioned slide mechanism has no measurable backlash. This is the only radial moving part of the assembly so adjustment has no negative impact on the tools balance.

The maintenance of the cartridge is limited to regularly flushing the mechanism with grease through a supplied grease gun. This prevents contamination and ensures perfect results from the accurate internal mechanism.
