Pecking (Cycle 1)

1) The tool drills from the “Current Position” to the first PECKING DEPTH at the programmed FEED RATE F.

2) When it reaches the first pecking depth, the tool retracts in rapid traverse FMAX to the starting position and advances again to the first PECKING DEPTH minus the advanced stop distance t.

3) The advance stop distance is automatically calculated by the control: At a total hole depth of up to 30mm :t = 0.6mm

At a total hole depth exceeding 30mm :t = hole depth / 50. Maximum advanced stop distance = 7mm.

4) The tool then advances with another infeed at the programmed FEED RATE F. 5) The TNC repeats this process (1 - 4) until the programmed TOTAL HOLE DEPTH is reached.

6) After a DWELL TIME at the bottom of the hole, the tool is returned to the starting position in rapid traverse FMAX for chip breaking.

NOTE: Program a positioning block for the starting point (hole center) in the working plane with RADIUS COMPENSATION RO.

Program a positioning block for the starting point in the tool axis (SET-UP CLEARANCE above the workpiece surface).

The sign (+ or -) for the cycle parameter TOTAL HOLE DEPTH determines the working direction.

⇒ SETUP CLEARANCE - (Incremental) Distance between tool tip (at start position) and workpiece surface.

⇒ TOTAL HOLE DEPTH - (Incremental) Distance between workpiece surface and bottom of the hole (tool tip).

⇒ PECKING DEPTH - (Incremental) Infeed per cut. The tool will drill to the DEPTH in one movement if :a) the PECKING DEPTH equals the TOTAL HOLE DEPTH. b) the PECKING DEPTH is greater than the TOTAL HOLE DEPTH.

⇒ DWELL TIME IN SECONDS - Amount of time the tool remains at the total hole depth for chip breaking.

Drilling (Cycle 200)

1) The TNC positions the tool in the tool axis at rapid traverse FMAX to the SET- UP CLEARANCE above the WORKPIECE SURFACE COORDINATE. 2) The tool drills to the first PLUNGING DEPTH at the programmed FEED RATE F.

3) The tool is retracted to SET-UP CLEARANCE in FMAX, remains there - if programmed - for the entered dwell time, and advances again in FMAX to 0.2mm above the first PLUNGING DEPTH.

4) The tool then drills deeper by the PLUNGING DEPTH at the programmed FEED RATE F.

5) The TNC repeats this process (2 - 4) until the programmed TOTAL HOLE DEPTH is reached.

6) At the hole bottom, the tool is retracted to SET-UP CLEARANCE or - if programmed - to the 2ND SET-UP CLEARANCE in rapid traverse FMAX. NOTE: Program a positioning block for the starting point (hole center) in the working plane with RADIUS COMPENSATION RO.

The sign (+ or -) for the cycle parameter DEPTH determines the working direction.

⇒ SETUP CLEARANCE Q200 - (Incremental) Distance between tool tip (at start position) and workpiece surface.

⇒ DEPTH Q201 - (Incremental) Distance between workpiece surface and bottom of the hole (tool tip).

⇒ FEED RATE FOR PLUNGING Q206 - Traversing speed of the tool during drilling.

⇒ PLUNGING DEPTH Q202 - (Incremental) Infeed per cut. The tool will drill to the DEPTH in one movement if :a) the PECKING DEPTH equals the TOTAL HOLE DEPTH. b) the PECKING DEPTH is greater than the TOTAL HOLE DEPTH.

⇒ DWELL TIME AT TOP Q210 - Amount of time the tool remains at the SET- UP CLEARANCE after having been retracted from the hole for chip release.

⇒ WORKPIECE SURFACE COORDINATE Q203 - (Absolute) Co-ordinate of workpiece surface.

⇒ 2ND SET-UP CLEARANCE Q204 - (Incremental) Co-ordinate in the tool axis at which no collision between tool and workpiece (clamping devices) can occur.

Reaming (Cycle 201)

1) The TNC positions the tool in the tool axis at rapid traverse FMAX to the SET- UP CLEARANCE above the WORKPIECE SURFACE COORDINATE. 2) The tool reams to the entered DEPTH at the programmed FEED RATE F. 3) If programmed, the tool remains at the hole bottom for the entered dwell time. 4) The tool then retracts to SET-UP CLEARANCE at the FEED RATE F , and from there - if programmed - to the 2ND SET-UP CLEARANCE in FMAX. NOTE: Program a positioning block for the starting point (hole center) in the working plane with RADIUS COMPENSATION RO.

The sign (+ or -) for the cycle parameter DEPTH determines the working direction.

⇒ SETUP CLEARANCE Q200 - (Incremental) Distance between tool tip (at start position) and workpiece surface.

⇒ DEPTH Q201 - (Incremental) Distance between workpiece surface and bottom of the hole (tool tip).

⇒ FEED RATE FOR PLUNGING Q206 - Traversing speed of the tool during drilling.

⇒ DWELL TIME AT DEPTH Q211 - Amount of time the tool remains at the DEPTH.

⇒ RETRACTION FEEDRATE Q208 - Traversing feedrate of tool when

retracting from the hole. If zero is entered the tool retracts at the reaming FEED RATE FOR PLUNGING.

⇒ WORKPIECE SURFACE COORDINATE Q203 - (Absolute) Co-ordinate of workpiece surface.

⇒ 2ND SET-UP CLEARANCE Q204 - (Incremental) Co-ordinate in the tool axis at which no collision between tool and workpiece (clamping devices) can occur.

Boring (Cycle 202)

1) The TNC positions the tool in the tool axis at rapid traverse FMAX to the SET- UP CLEARANCE above the WORKPIECE SURFACE COORDINATE. 2) The tool bores to the entered DEPTH at the programmed FEED RATE F. 3) If programmed, the tool remains at the hole bottom for the entered dwell time. 4) The TNC then orientates the spindle to the zero degree position with an orientated stop.

5) If retraction is selected, the tool retracts in the programmed direction by 0.2mm (fixed value).

6) The tool then retracts to SET-UP CLEARANCE at the RETRACTION FEED RATE , and from there - if programmed - to the 2ND SET-UP CLEARANCE in FMAX.

NOTE: Program a positioning block for the starting point (hole center) in the working plane with RADIUS COMPENSATION RO.

⇒ DISENGAGING DIRECTION Q214 - Direction to clear bore. 0 = Do not retract the tool

1 = Retract the tool in the negative main axis direction. 2 = Retract the tool in the negative secondary axis direction. 3 = Retract the tool in the positive main axis direction. 4 = Retract the tool in the positive secondary axis direction.

NOTE: Check the position of the tool tip when you program a spindle orientation to zero degrees. Align the tool tip so that it is parallel to a coordinate axis. Select a DISENGAGING DIRECTION in which the tool moves away from the edge of the hole.
