Our engineering technology division’s task for this customer involved the automation and cycle time optimization of a precision machine tool for cutting profiled bars from special materials. The core technology is the six-axis control by means of a Simodrive servo controller with absolute position encoder, as well as the control of the cutting and grinding wheels by a frequency converter.
Together with the operator and the machine manufacturers, the desired processes and boundary conditions were developed and described in a specification sheet, along with calculations and designs.
The operator places up to 30 profile bars on so-called prism holders in the staging area. The number, profile and length of the bars are also captured here.
The machine removes the work piece in the most efficient way and transfers it to the machining area. Here, after a special pre-treatment, the bars are moved one by one to the machining station by means of a portal pick-up system. Speed-controlled synchronised cutting and grinding wheels precisely slice and mill the bars according to a selectable recipe. Laser light barriers monitor the machining process for possible breakage. After machining, the samples are rinsed and dried. Selective status displays indicate the status of each individual bar. Once the whole of the first batch has been machined, the process repeats with the next batch. The panel system selectively records and archives data on the workpiece and tools, recipes, handling times, material use and operator interventions for each batch.
