In 1961, we developed the radial boring machine equipped with an NC controller in collaboration with an electric manufacturer, and have always provided customers with industry-leading machines, controller, and technology.
In this article, we will introduce the history of our in-house developed numerical controller OSP (Okuma Sampling Path Control).
In 1963, we believe that the method of not forgetting the origin and the tool position even when the power is turned off is excellent in both operability and reliability, and we have developed an “Absolute Position Detection” NC controller.

After that, we started software control with the aim of achieving high reliability and functionality, and in 1972 developed the practical CNC with the built-in mini computer in advance of the world.
In addition, we have developed a servo motor in 1982, and manufactured the motor, servo drive unit, detector, and other units in-house to achieve high-performance and harmonious control.
Currently, we are providing intelligent technology typified by the Thermo-Friendly Concept to our customers, and are proceeding with the technological development that is actually needed in the operation field.

The latest controller, OSP-P300A, contributes to the “Manufacturing Revolution” of customers, such as the OSP suite with the information and operability necessary for processing sites, and the Connect Plan that supports analysis for improving the factory operation rate.
Machine shops get top priority with easy-to-use OSP control
An Intelligent CNC designed for the Shop Floor
Okuma made these features a reality by building on its machining expertise, based on requests received from customers in the machine shop. These features are filled with intelligence that enhance the “strength in the field” that the CNC control can accomplish because they are created by the premier machine-tool manufacturer.

Turn-Cut Guide (Optional)
Making new machining technology simpler and easier to use
Turn-Cut is an innovation from Okuma that enables turning using the milling spindle. It makes it possible to create surfaces that taper and have any varying diameter shape using a single tool through advanced synchronized control, as well as machining inner and outer diameters greater than the largest tool diameter. After the cutting conditions that follow graphic guidance have been set, inputting the spindle speed yields calculation of roundness at that speed. Inputting roundness yields calculation of the optimal spindle speed for achieving the input value.
Spindle Output Monitor
Increased productivity through visualization of motor power reserve
The specified spindle output (red line: short time rating, green line: continuous rating) and the spindle output in current cutting (blue circle) are simultaneously displayed on the screen, for real-time view of power reserve during cutting. This allows speeding up cutting by increasing the spindle speed or feed rate while monitoring the graph to ensure that the blue circle does not cross the red or green lines.

Chuck Pressure Calculation
Calculation of required theoretical values based on input of chuck and cylinder types
Proper chucking pressure is essential for maintaining both work safety and machining accuracy, but calculation can be complicated and troublesome. With this new feature, selecting the chuck and cylinder type and setting the cutting conditions according to the graphical guidance yields a calculation of the theoretical chuck pressure for ensuring the required grip force under specified conditions.

With the feeling of using a smart phone
Smooth, comfortable operation
Improved rendering performance and use of a multi-touch panel achieve intuitive graphical operation. Moving, enlarging, reducing, and rotating 3D models, as well as list views of tool data, programs, and other information can be accomplished through smooth, speedy operations with the same feel as using a smart phone.

Momentum scrolling for finding target items with ease
When scrolling rapidly through screens, motion continues even after the finger releases the screen. This can make it easier to find a target item in a list view of items, such as tools or program files.
● Functions accessible using multi-touch panel operations:Collision Avoidance System, Easy Modeling, Advanced One-Touch IGF, PDF/STL Viewer, data views, program-file list-view operations and program editing operations.
