Control

The Röders Control RMS6

PC-based control

• Only a few operating elements for extremely simple operation of the PC-based control
• USB interface, indus­trial mouse and 19” TFT screen standard
• NC-programs in ISO-format or Heidenhain®#-format (with limited scope), mixed code also possible
• Compa­tible with INDUSTRY 4.0
• Quick familia­rization and operation using icons, text and hotkeys

Vibration monitoring of the spindle

The use of high-speed spindles requires a limitation of the maximum spindle load in order to avoid bearing damage or a severe reduction in service life. Optio­nally, the spindles can be equipped with vibration sensors. A function in the control can be activated that automa­ti­cally reduces the feed and, if necessary, the RPM of the spindle in the event of high vibra­tions. In addition, a coloured graphic illus­tration of the vibra­tions along the milling path is possible. As a result, any areas in the milling path with high vibra­tions can easily be identified and can safely be avoided in recurring machining processes by adapting the CAM programming.

Compensation of spindle elongation

Röders machines have been known for years for their external high-precision sensor for spindle elongation compen­sation. A holder fixed in the casting of the Z‑axis and kept geome­tri­cally stable with a tempering circuit carries a sensor at the end that contactless measures the displa­cement of the rotating spindle shaft in nano meter range. This is compen­sated for in the control system. Since the heat from the spindle shaft is trans­ferred into the tool holder and it also lengthens as a result, a short warm-up phase had to be programmed for high-precision machining appli­ca­tions before starting the machining operation.

Meanwhile, the Röders techni­cians have succeeded in modelling the dynamic heating process directly after the spindle has accele­rated to full RPM, so that with the new option Spindle Compen­sation PLUS a warm-up phase can be skipped completely in many applications.

Röders is partner of the umati initiative of the German machine tool association VDW (umati = universal machine tool interface). The umati interface enables a standar­dized data transfer to the machines of numerous suppliers. umati is an essential step towards industry 4.0.

Control technology optimised for HSC

Outstanding charac­te­ristics of the Röders RMS6 control:

• Block processing time < 0.1 ms
• Look ahead > 10,000 blocks
• Conti­nuously improved spline inter­po­lation and speed determination

Performance increase through control updates

Newest control versions also for older machines(from year of manufacture 1995) available at low cost with the special Röders update service

→ Higher precision, better surface quality and signi­fi­cantly shorter machining times

→ Easier operation, as all Röders machines can have the same control version despite different years of production

Automatic minimisation of vibrations

Automatic spindle speed optimi­sation by the machine within a user-selec­table range in order to minimise vibra­tions and achieve the highest possible surface quality; patented

Tangential transitions

Patented function to avoid offsets in transi­tional areas if several different tools are used for machining

• Automatic modifi­cation of the machining programs for tangential transitions

Postprocessors

• Simple individual programing of postpro­cessors for all CAD/CAM-systems with the help of the Röders postpro­cessor handbook
• Postpro­cessors for all common CAM systems available
• Complete output of all NC-parameters by the CAM-system
  → Programing at the machine control not necessary

• Processing of ISO-NC-programs (G‑code) or Heidenhain®#-NC-programs (with limited scope) possible
• very short familia­rization time
• Basic-like programming for special appli­ca­tions possible
• Changeover to Röders control very simple because no new programming language has to be learnt
• Also a mixed use of ISO-NC-commands and Heidenhain®#-NC-commands is allowed

Optimised use of tools

Numerous functions for optimised use of tools

• Sister tools
• Wear criteria
• Maximum tool life travel
• Measu­rement strategies
• Geometry identi­fi­cation and test
• Adminis­tration and import of tool types etc.

Further control functions

• RACECUT® – Perfor­mance boost in machining 3D contours
• 32 kHz drive control frequency and an optimized tool path planning in the control lead to signi­ficant reduc­tions of machining times, up to 20% while surface quality and precision remain equal
• Since the energy (power) consumption of the machine is relatively constant regardless of the selected dynamics, the energy saving is of the same amount
