Tosnuc 888 Controller

ELK GROVE VILLAGE, IL - Toshiba's new user-friendly Tosnuc 888 CNC controller is designed with unique functions that are especially suited for the Die & Mold Industry. Available exclusively with Toshiba's MPF-C Series and BP-150.822 and NX-76 machines, the controller effectively provides smooth, fast, safe, and easy operation.

For example, featuring CNC Shape, the Tosnuc 888 forecasts a workpiece profile based on forward data and then calculates acceleration and deceleration to maintain high accuracy and high speed. The result is a smoother surface finish. CNC Shape also automatically changes feed rates in corners and at the corner's edge to avoid machine shock.

Efficiency is enhanced with the Tosnuc's SF Function. It minimizes the need for hand finishing by interpolating between each cutting point by quadratic or cubic curve. To maintain constant chip load, the SF Function allows for an automatic change in feed rate and spindle speed relative to cutter contact diameter. In Mode 1, RPM and feed rate are based on cutter contact radius; while in Mode 2, RPM and feed rate are based on acceleration and deceleration. The SF Function achieves a smoother surface and reduced cutter wear.

The Tosnuc 888's Zone Machining Function allows a change in the Z-axis direction or cutting condition in a zone set in advance without changing NC data. Time is saved, as only one program is needed to machine two different types of materials. Zone Machining also automatically changes spindle speeds and feed rates in a specified zone.

Thanks to a Timer Cycle Function, an operator can set a check point during machining for tool wear without changing NC data. Based on tool wear, the machine either continues using the current tool or selects a spare tool.

A 3-dimensional tool path is created in the CNC controller using NURBS Interpolation. An excellent finish surface and smaller program size are advantages gained from the Tosnuc 888's NURBS Interpolation Function.

What's more, the innovative Robo Drill Function uses a special tool and control method to make inclined holes without special attachments. In addition, an In Corner Cutting Function (currently under development) will machine sharp edge corners by using a rotational tool. This will reduce EDM operation and lead time.
