How do you determine the quality of your parts preocessed by a servopress? In contrast to conventional practices of inspecting the finished part for defects, our system can combine the Force and Distance measure provided by the sensors embedded in our servo press. The system in this way receives the necessary data to monitor the process and provides the capability to create a warning system. Our systems have the capability of measuring the process variation during production, thus detecting problems at the source before they become quality issues, thanks to the capability of combined control of two parameters Force vs Displacement. Comparisons can now be made with the waveforms generated by a masterpiece preloaded in the systems. This information is very important because it can be compared to a mathematical model of your quality standards. In other words if an acceptable process is known, our system can be calibrated to repeat the known process and produce parts that conform and the process is verifiable consistent and repeatable. A constant control of Force vs Distance indicates that the resulting part has been produced according to the previously verified acceptable part. By continuously monitoring the measurement parameters of the servo press, it is possible to detect variances that can mean the process is no longer quality capable. Catching defects at the source gives manufacturers the confidence that only good parts are shipped to the customers.
APM-BA is a process monitoring software developed to monitoring the pressing applications. The software is installed in the CPU of the intelligent servo drive Bosch Rexroth® and is possible set up the pressing parameters trough our APM-PC ToolKit. APM-BA is configured as slave machine and its flexibility allow several applications in different industries. Our System can be connected to all kind of PLC (master) because the dialogue with the APM station is trough discrete digital Inputs/Outputs. As soon as you install an Auloma servo press with APM, you can verify the simplicity of the hardware installation and the few time spent for configuring and set up. Further this our technical centre in India can provide to all customer in this country a faster and reliable service in Hindi, Urdu or English language.
APM-BA own three modalities to control the press ram. The set up of each program is easy and friendly. In few minutes is possible set up the press according your application. The three modalities allow a ram control to press at the right force, at the right position and at the right relative position from a force signal trigger. the ram program is saved in the memory of the servo drive unit.
The brain of the APM-BA is the powerful CPU that allow a faster analysis of the data gathered from the press sensors. The APM software produce a faster analysis of all data provided by the servo press. The press waveform results are controlled by multiple tolerance off set zones or by an envelope that wrapping the trajectory. Thanks to this method if the process is repeatable the analysis results are repeatable also and by the comparison of a masterpiece waveform the APM can decide in few milliseconds if the parts are correct or wrong.
The APM displays all informations about press program and test result on a Windows ® PC machine with APM-BA toll kit installed. Thanks to the icons on the software interface is easy display tables and graphs. The navigation inside the APM-BA Toll kit is protected by password and allow different set up level according the permission.
The APM-BA can provide the process signature data in CSV ( Comma Separated Value ) format to an external data storage. The CSV data can be used for SPM ( Statistic Process Management ) or SPC ( Statistic Process Control ) and can be processed by many ERP, MRP and spread sheet )
The best yield obtained by Auloma servo press is when all analysis data provided are saved and analysed in a PC machine. Statistical analysis of your data allow an aware knowledge of your quality trend. Through APM-BA ToolKit whichever PC machine can set up the press operations but can also save and see all analysis data. With a good organization of the archive folders is possible research the data stored through a DB and then analysed by Statistic Process Management installed.
APM-BA displays a templates where is possible edit the parameters to control the servo press ram. The templates propose an editor where is possible load the single functions from the default library to program a recipe with a maximum of 16 breakpoints. The program developed can execute three different kind of press control:
This flexibility allow toll changing and execute two or more kind of controls in the same cycle.
The APM-BA displays a menu to setting the force limits on wafeform
High level status screen allows operator and supervisors to quickly assess the part test status. The program displays until four presses in run. Each menu displays the instantaneous value of force and position of each ram. The central lower menu displays the press cycle results.
The APM-BA provide each cycle the curves produced by the data gathered. The curve is displayed on (x)(y) graph, where in (x) there is the ram stroke scale and in (y) the force. The view of the curve is aided by a smart zoom function and pan function. The off set force limit settled on the curves can be displayed through the properly buttons on the screen.
The APM save each cycle result in two different CSV files. The 1 st file provides the raw data to identify the historical period, the 2nd file provides the raw data about the analysis. Both files are saved on the respective folder path. The analysis history is displayed below the curve templates and is possible displays each historical curves through a flaggable field
The analysis results can be plot in HTML format to generate useful documents
