Today’s machine tools are sophisticated units with many self-diagnostic capabilities left untapped. As a result of the high quality of components and design, machine failure seldom occurs. When it does, many maintenance technicians have little experience with these machines to draw upon. Troubleshooting an Okuma machine tool with the OSP P300 series control is made easier when you understand and use the maintenance and troubleshooting capabilities of the control. Here are 5 tips to help you get started.
The Maintenance Monitor displays items for inspections before starting daily operation and regular inspections and the rough estimate of inspection timing. Touching the [INFO] button displays the PDF instruction manual file of relevant maintenance items.
- Utilize the User Maintenance Function. This allows you to provide reminders to your operator for daily tasks as well as Preventive Maintenance. Coupled with the Scheduled Maintenance app it allows planning and implementation of a wide range of proactive service tasks.
- When trouble occurs, the Self Diagnostic Function provides Alarm messages directing you to the specific area of the issue. The included Check Function will enable you see the I/O conditions, Axis Data, and specific messages about the machine condition. The Machine Diagnosis Screen offers insight to which machine condition is not fulfilled. These shortcuts can save valuable time when troubleshooting in a production environment.
- PLC Monitor function is an important tool when working on intermittent problems. This function allows visibility of the PLC Ladder and has the ability to monitor specific labels in the ladder during operation.
- All of the manuals that apply to your machine are now loaded on the machine and accessible to read via the control. The OSP Maintenance manual that is provided, details how the diagnostic functions operate. Additionally, the manual offers a number of common maintenance part replacement instructions with annotated diagrams.
- Back up your data to a removable memory device often. In the unlikely occurrence of a hard drive failure or corruption of your files, you’ll have a recent copy of your machine data and parameters as a basis for recovery.
However, many Okuma customers no longer keep maintenance technicians on staff. In either case, it is wise to understand the basics of your control. Review the maintenance manual when calling your local distributor for technical support. Familiarity with the basics will allow clear communication of the problem. In many cases, the solution may be provided over the phone as opposed to an onsite service call.
Serves as a reminder for the operator to perform scheduled maintenance as well as a daily reminder for various service -related tasks.
The Scheduled Maintenance Application helps in keeping your Okuma machines at top performances. The application runs in background and reminds the machine operator when maintenance tasks as due. Every Okuma machine tool has two different maintenance tasks: after-installation and periodical. The after installation tasks happens only once after the machine goes in operation the first time. After that, the periodical tasks take over for the machine life.
The Operation and Maintenance manual provided with your machine contains all the information needed to know about your machine maintenance. This application is not a replacement of the manual, but it is intended to provide reminders about incoming maintenance events. Always refer to the machine Operation and Maintenance manual when performing maintenance tasks.
On top of the scheduled maintenance reminders, the application allows the user to show daily tasks or checks that the machine operator follows at the start of the working day, for example, check the coolant level, put grease in the chuck, and so on.
The application has two operative modes: CNC mode and PC mode. The application automatically choses the mode depending if the user installs the application on a P200/P300 CNC with API up and running or on a Windows machine (PC, laptop, or tablet). When the application is installed on a CNC, the machine model and serial number are taken from querying the API and the user has to specify the installation date of the machine.
If the application is installed on a Windows machines, the user has the ability to specify one or more machines and their respective serial numbers and installation dates. When in PC mode, the application monitors the scheduled maintenance tasks of more than one machine chosen by the user. The user must input the machine serial number so the application can uniquely identify each machine. The daily reminders functionality is still available in PC mode, but is disabled by default.
