Definition of a custom chip breaker document

With this document we can define a new sequence of chip breaker.

Putting this document in a user library allows us to access to this document in all the projects.

In this document we are going to define the steps to realize a set of drillings.

Each drilling with a depth (P)can contain an ascent (R)a descent (D) a dwell, or a rotation direction.

A first set of icon allows to define the action to realize.

Ascent Descent Machining Dwell Rotation direction Coolant

We must then select between one of those 6 actions and define its parameters.

To validate and create an action click on the icon a color graph allows to simulate the action.

The following example shows a sequence of 5 actions: "Machining", "Ascent", "Dwell", "Rotation direction" and "Descent".

Description of the 6 actions:

Machining :

This option allows to create a drilling with a customized depth.

Choose the type of depth

	The depth is expressed as a percentage of the diameter of the tool used to machine the hole.
	The depth is defined by a hole depth percentage
	The depth is not linked to the hole, it's a defined value in mm. However the sum of the depths must be less than the actual total drilling depth.
	The depth is expressed in percentage of the total machining depth. That is the depth of the hole with stock included more safety distance.

Set the feed rate type

The color code in the graph is yellow

The retract :

This action allows to realize an ascent in Z.

Set the feed rate type

choose the type of retract

	Retract plane The altitude is the clearance plane defined in the drilling operation.
	Clearance Distance It is the clearance distance defined in the drilling operation.
	Offset This value is defined in relative in the action of "Ascent".
	Altitude hole top This value is defined relative to the top of the selected geometry for drilling.

The color code in the graph is green.

Dwell :

This option allows to create a delay.

Simply gives the value of the dwell.

The color code in the graph is blue.

Rotation direction :

This action allows a rotation direction change or a spindle stop.

Choose among the codes M3, M4 or M5.

Spindle rate factor

When the box is checked it is possible to define a factor to apply on the initial spindle rate defined in the cutting conditions of the operation.

Spindle rate factor

When the box is unchecked it is possible to define a custom spindle rate.

The direction change is symbolized by a point in the graph with a reminder of the code.

Plunge :

This action allows to realize a plunge in Z.

Set the feed rate type

choose the type of plunge

Reach safety distance

The descent is realized until the stock + safety distance.

Offset

This value is defined in relative in the action of "Descent".

Clearance Distance

The descent is realized following the safety distance value defined in the drilling operation.

The color code in the graph is red.

The coolant :

It allows to activate or not the coolant with the desired mode.At the end 5 coolant modes can be use.The coolant pressure unit is the bar.

None Jet Mist Center Micro lub Air

The "Loop" option allows to repeat a sequence from a step to another one to have the drilling fully machined.

Loop	Loop

It allows to add an action at the end of the sequence.

Select the type of action, set the parameters and click on the icon to add it.

It allows to add an action in a sequence.

Click in the board of the actions to select the position, define the type of action and the parameters then to click the icon.

It allows to delete a step.

Click in the board of the actions to select the action to be deleted, then to click the icon.

It allows to modify a step.

Click in the board of the actions to select the action to be modified, then to click the icon.

Configuration

It allows to set the characteristics of the hole, altitudes and feed rates for the graph.

	Allows to switch from a blind hole to a through hole.
	Allows to resize the preview.
