The control of i/18i/21i model B series has strong expansion control function, and can support high-speed and high-precision processing. With FANUC's latest rare magneto AC servo motor is series, it can support smooth rotation and high acceleration and deceleration capacity. This CNC can greatly increase the competitiveness of products

(1) the increase of the maximum number of control axes

this is because the peripheral parallel devices of the machine have an increasing trend. For example, ATC and load axes and other additional objects are added to form an inclined workbench to increase the added value of the product. The composition of the system can greatly simplify these control devices, and it is best to be controlled by CNC itself. 18i model B5 (number of simultaneous control axes =5) and 18i model B (number of simultaneous control axes =4) expanded from 6 to 8. 21i model B (number of simultaneous control axes =4) expands from 4 to 5

(2) nano smooth control

16i/18i-m model B series and 18i-m model B5 add the newly published nano smooth inter filling ability, which can obtain the best quality on the finish machined surface on the mold surface and reduce the polishing time for post-treatment

。 CNC is processed by the output line segments of cad/cam system to obtain the desired shape. Then, the NURBS curve is processed with a tolerance of 1nm

。 The NUBRS curve generated by the gap is filled in nanometers

(3) AI nano profile control for lathes

ai nano profile control was originally provided for milling machines, but now it is also newly provided for 16i/18i/21i-t model B. If nano gap is used in lathe processing, higher precision machining surface will be produced

the feature of the testing software function of the acceleration speed control plastic tensile testing machine is to improve the processing speed and reduce mechanical vibration. The acceleration and deceleration can be controlled during processing to reduce the impulse, and this goal can be achieved by changing the curvature change during the acceleration time

(4) the function of servo guide mate

the function of servo guide on PC has been added to 16i/18i/21i model B, which can be used to check the adjustment status of spindle and servo on the CNC window. It is an effective tool for MTB to check the accuracy of mass production machine, and end users can be used to check the accuracy change of machinery after years of processing. This function provides the following analysis mode:

. The time base displays

. Contour error display

. The mobile mode displays

4 New function (for various types of 5-axis processing machines, FANUC 16i-mb/18i-mb5 southbound express 5-axis processing)

the current type of 5-axis processing function is equipped with a new high-speed RISC processor. These functions can be used in a variety of 5-axis processing machines, such as head rotation type, workbench rotation type, and hybrid type

features:

. 5-axis machining tool center point control

when the tool axis has a tilt change, the movement of the tool tip center point can follow the program path according to the specified feed rate. With this function, when the tool length changes, there is no need to change the processing program

。 5-axis machining tool diameter correction

3D tool diameter correction can be corrected on the plane perpendicular to the tool, and Euler angle correction can also be used. With this function, when the tool diameter changes, there is no need to change the processing program

。 The inclined plane processing instruction

specifies an inclined plane as a processing plane and releases the program on this plane (x, y). The processing action can be automatically converted to this inclined plane, and the action of the rotation axis can be automatically controlled to be perpendicular to the inclined plane. With this function, the processing program can be easily made on the inclined plane

。 Manual feed for 5-axis machining

with this function, the tool can be manually moved along the inclined plane or the direction of the tool axis

this function can make the rotating shaft move manually without changing the position of the tool nose. With this function, it becomes very easy to process the inclined surface

5. New functions (improve the surface quality of finish machining and reduce the processing time)

acceleration speed control is provided on FANUC 16i/18i MB5/18i MB Series, with nano instructions that can perform position calculation and servo control. Its function is to increase the surface quality of finish machining and reduce the processing time

(acceleration refers to the acceleration change rate)

characteristics:

. Each servo axis can consider the acceleration to determine the feed rate

the cutting speed can automatically decelerate to the best speed at a specific position to obtain a smoother shape, but it will produce a large amount of impulse, resulting in mechanical vibration. For example, the shape of the program is a straight-line single segment connected with a circular arc single segment. If the impulse generated by the deceleration of the two single segments can be automatically avoided, the quality of the finish machined surface can be improved, When the cutting speed is reached, there can be only slight vibration in this place, so that the feed speed can be increased to reduce the processing time

。 Smooth bell acceleration/deceleration

make the acceleration/deceleration achieve smooth curvature change, and reduce vibration with smoother control, so as to obtain a better machined surface
