DOOSAN-FANUC HIGH SPEED MODE

FANUC's latest High Speed modes are AICC and AIAPC- AI Contour Control and AI Advanced Preview Control.AI does not refer to "Artificial Intellegence".AI represents FANUC's Alpha I Series Servo System.There are differences between the two AI modes.However, the syntax for using them is exactly the same.(For detailed data on the two specifications, contact FANUC directly.)

AICC/AIAPC Format:

Enable: G05.1 Q1 Rx

Where:-Rxx provides the user with the option of selecting from 10 fixed settings (R1 -R10) which contrast Tool PathSpeed (feedrate) with Positioning Accuracy,

G05.1 Q1 R1 - Toolpath Speed has priority over Positioning AccuracyG05.1 Q1 R2G05.1 Q1 R3G05.1 Q1 R4G05.1 Q1 R5 - Tool Path Speed and Positioning Accuracy have Equal PriorityG05.1 Q1 R6G05.1 Q1 R7G05.1 Q1 R8G05.1 Q1 R9G05.1 Q1 R10 - Positioning Accuracy has priority over Tool Path Speed

R1-R2: Smoother Axis Motion and Improved Accuracy.R3-R5: Die & Mold - Roughing.R6-R8: Die & Mold - Semi-Finish.R9-R10: Best Accuracy, Finish, Form & smooth axis motions.

R1 = Rough MachiningR10 = Finish Machining

(Using R1, a 90° corner produced at a feedrate of 10,000 mm/min will produce an approximate deviation of 0.15mm.)

Cancel: G05.1 Q0

Practical Application

Application Case 1: 2D ContouringAICC/AIAPC Addresses the typical corner rounding or overshoot problems when feedrate is high or feature is small.

Applications Case 2: 3D SurfacingAICC/AIAPC will keep the contouring profile more accurate.

There are 4 Simple rules that should be followed for successful use of AICC/AIAPC.

1) Make sure G49 is called before the execution of G05.1 Q1 Rx2) G05.1 Q1 Rx must be engaged BEFORE G43-Tool Length Comp3) AICC and AIAPC need to be turned on and off for each tool4) AICC and AIAPC does not apply to canned drilling cycles
