Refer to your machine manual.
Machine and control must be specially prepared by the machine manufacturer for use of this cycle.
This cycle is effective only for machines with servo-controlled spindle.
Special boring bars for upward cutting are required for this cycle.
This cycle allows counterbores to be machined from the underside of the workpiece.
Enter the tool length measured up to the lower edge of the boring bar, not the cutting edge.
Help graphic | Parameter |
---|---|
Q200 Set-up clearance? Distance between tool tip and workpiece surface. This value has an incremental effect. Input: 0...99999.9999 or PREDEF | |
Q249 Depth of counterbore? Distance between underside of workpiece and the top of hole. A positive sign means the hole will be bored in the positive spindle axis direction. This value has an incremental effect. Input: –99999.9999...+99999.9999 | |
Q250 Material thickness? Height of the workpiece. Enter an incremental value. Input: 0.0001...99999.9999 | |
Q251 Tool edge off-center distance? Off-center distance of the boring bar. Refer to the tool data sheet. This value has an incremental effect. Input: 0.0001...99999.9999 | |
Q252 Tool edge height? Distance between underside of boring bar and main cutting tooth. Refer to the tool data sheet. This value has an incremental effect. | |
Q253 Feed rate for pre-positioning? Traversing speed of the tool in mm/min when plunging or when retracting. Input: 0...99999.9999 or FMAX, FAUTO, PREDEF | |
Q254 Feed rate for counterboring? Traversing speed of the tool in mm/min during counterboring Input: 0...99999.999 or FAUTO, FU | |
Q255 Dwell time in secs.? Dwell time in seconds at the bottom of the bore hole Input: 0...99999 | |
Q203 Workpiece surface coordinate? Coordinate on the workpiece surface referenced to the active datum. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q204 2nd set-up clearance? Distance in the tool axis between tool and workpiece (fixtures) at which no collision can occur. This value has an incremental effect. Input: 0...99999.9999 or PREDEF | |
Q214 Disengaging directn (0/1/2/3/4)? Specify the direction in which the control offsets the tool by the off-center distance (after orienting the spindle). Inputting 0 is not permitted 1: Retract tool in negative main axis direction 2: Retract tool in negative secondary axis direction 3: Retract tool in positive main axis direction 4: Retract tool in positive secondary axis direction Input: 1, 2, 3, 4 | |
Q336 Angle for spindle orientation? Angle at which the control positions the tool before it is plunged into or retracted from the bore hole This value has an absolute effect. Input: 0...360 |
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
