Required input parameters

Input parameters

Description

@P1

Reference plane (absolute)

@P2

Retraction plane (absolute)

@P3

Safety clearance (relative to the reference plane, unsigned)

@P4

Final drilling depth (relative to the reference plane, unsigned)

@P31

Machining mode:

1: chip breaking

2: chip evacuation

@P61

Return clearance for chip breaking and holding distance after chip evacuation (unsigned)

Optional input parameters

Input parameters

Description

@P10

First feed depth / depth infeed in mm/inch (unsigned)

If the parameter "Number of infeeds" (@P11) is deactivated and the parameter “First feed depth” (@P10) is activated, @P10 specifies a depth infeed in mm/inch.

@P11

Number of infeeds (unsigned)

Maximum infeed depth is calculated from [depth (@P4) / number of infeeds (@P11)]

@P17

Dwell time at final drilling depth (in seconds)

@P87

Point angle of the drilling tool

If the point angle is specified, the dimension from the point to the lateral surface of the tool is calculation and added to the final drilling depth.

The drill radius is read from the tool memory to calculate the new final drilling depth. The radius may not be 0.

@P92

Retraction mode:

0: retract at rapid traverse (default)

1: retract at feed rate

@P132

Feed rate for infeed in Z (values in mm/min, inch/min)

Default value = Active feed rate at cycle call

@P172

Feed rate for first infeed in Z (specified in mm/min, inch/min)

Default value = Active feed rate at cycle call

@P173

Z start position in pilot hole (relative to reference plane)

@P174

Feed rate of safety clearance to Z start position in pilot hole (specified in mm/min, inch/min)

This parameter must be specified if a Z start position in the pilot hole was specified.

@P175

Spindle speed for deep hole drilling

This parameter must be specified if a Z start position in the pilot hole was specified.

@P176

Dwell time to adapt spindle speed (specified in seconds, default = 2)

@P177

Feed rate reduction / feed rate increase in every Z infeed (specified as percentage)

If the value is positive (e.g. 10), the feed is increased by this percentage value for each Z infeed.

If the value is negative (e.g. -10), the feed is reduced by this percentage value for each Z infeed.

n total, 50% of the original feed rate is not undershot or exceeded.

@P178

Reduction in the depth infeed (specified as a percentage)

Reduces the depth infeed after the first infeed depth as a percentage until the ”Minimum infeed” @P179 is reached.

@P11 may not be active.

@P179

Minimum infeed when depth infeed reduction is active (required if @P178 is active)

@P180

Additional through-drilling depth (is added to final drilling depth @P4)

@P181

Feed for through-drilling (required if @P180 is active)

@P182

Activate breakthrough detection. For more information, see below.

0: breakthrough detection inactive (default)

1: breakthrough detection active

For more information on pilot hole drilling and the additional through-drilling depth, see section Process.

It is recommended to use the Syntax check to verify whether the input parameters are correctly assigned.

Breakthrough detection

The breakthrough detection (@P182) function stops drilling operations after a breakthrough is detected. Movements in the form of a measuring block (G100) are therefore executed during machining. If a probe signal occurs during the process, the drilling operation is interrupted and the tool is retracted to the retraction plane in rapid traverse after the specified dwell time.

Attention

attention

If breakthrough detection is active, measuring mode 1 is activated in the cycle.
