Entry/Exit

The following Entry/Exit tab is displayed for the 2½ Axis Engraving operation. Entry and Exit determines the way in which tool enters and leaves the part geometry. MILL Module allows you to specify how the cutter approaches, engages, retracts and departs when starting and stopping a cut.

tog_minusEntry Motions

The Entry Motions section can be used to control how the cutter enters during the cutting process. You can choose to approach vertically and specify an Approach Distance or retract by choosing the None option. Alternatively, a 3D Entry can be specified for the Engage and Retract motions.

•None

Do not use a Entry Motion.  The tool will plunge into the stock at the current start point location.

No Entry Motion

No Entry Motion

•Line/Arc
The 3D Entry motion consists of an Approach Motion and an Engage Motion.

This allows you to specify a straight Vertical Distance (D) above the cutting start point..      

Vertical Approach (D)

Vertical Approach (D)

For Linear the cutter follows a linear ramp motion from the Vertical Distance (D) and engages the part at Angle (A).  Specify Length (L) and Angle (A).

Engage Motion=Linear

Engage Motion=Linear

•Along Path  

This is Angle (A) when the entry motion is set to Along Path.  It begins at Height (H) and ends at the cut start point.  During this move the tool travels at the Engage (Ef) feed rate.

Angle (A)

tog_minusExit Motions

The Exit Motions section can be used to control how the cutter exits during the cutting process. You can choose to retract vertically or using lines and arcs.

•None
Set Exit Motions to None and the tool will retract from the stock at the endpoint of the toolpath.

•Line/Arc

The Exit Motions consist of a Retract motion followed by a Departure motion. The departure motion is a linear motion.

Linear

Radial

Retract Motion  

The retract motion can be either a Radial (arc) motion or a Linear motion at an angle.

Linear

Enter the retract motion Length (L) and Angle (A).

Radial

Enter the retract motion Radius (R).

Departure Motion  

The departure motion is a linear motion specified by enter the Vertical Distance (D) value.
