AxiGrooves

AxiGrooves are axisymmetric GCDs that represent gears, splines, sprockets, and flutes. Child GCDs of an AxiGroove include the bottoms and sides of the tooth valleys. They do not include the tops of the teeth, and they do not include surfaces normal to the axis of rotation. See the section "Working with Gears, Splines, Sprockets, and Flutes" in the aPriori Cost Model Guide for more information. The GCD details include:

Cost drivers		Description
GCD	Name	The name and number that identifies the GCD. This information is an identifier only and is not used in any cost calculation.
Properties	Approach From	Ap direction of approach of the machine tool: OD (from the outside), ID (from the inside), or NONE.
	Axial Length (mm)	Length of the AxiGroove along turning axis in millimeters.
	Cone Angle (deg)	Cone angle of the AxiGroove in degrees. This is one half the apex angle of the AxiGroove’s root cone. (The gear’s axis of rotation is the root cone’s axis of symmetry. The surface of the root cone coincides with the bottoms of the tooth valleys.) The angle is 0 for cylindrical AxiGrooves, positive for conical AxiGrooves, and -1 if the valley profile is not cylindrical or conical.
	Distance To Shoulder A (mm)	Distance to the shoulder along the turning axis (in direction A) in millimeters. For external AxiGrooves, this is the distance between the end of the AxiGroove and the closest point on the turning profile that is higher than the valleys between teeth. For internal AxiGrooves, it is the distance to the closest point on the turning profile that is lower than the tooth valleys. A dash, -, is displayed when there is no shoulder.
	Distance To Shoulder B (mm)	Distance to the shoulder along the turning axis (in direction B) in millimeters. For external AxiGrooves, this is the distance between the end of the AxiGroove and the closest point on the turning profile that is higher than the valleys between teeth. For internal AxiGrooves, it is the distance to the closest point on the turning profile that is lower than the tooth valleys. It is -1 when there is no shoulder.
	Groove Depth (mm)	Depth of the grooves in millimeters.
	Helix Angle (deg)	Helix angle of the AxiGroove in degrees. This is positive for right-handed AxiGrooves, and negative for left-handed AxiGrooves.
	Helix Total Twist Angle (deg)	Total twist of the AxiGroove in degrees. This is set to -1 when either of the following holds:  AxiGroove’s inner surface is neither cylindrical nor conical.  For external AxiGrooves, the bottom groove points are not on a spiral; for internal AxiGrooves, the top groove points are not on a spiral.
	Max Diameter (mm)	Maximum diameter of the AxiGroove in millimeters. This is twice the maximum distance from a tooth or valley surface to the turning axis.
	Min Diameter (mm)	Minimum diameter of the AxiGroove in millimeters. This is twice the minimum distance from a tooth or valley surface to the turning axis.
	Number of Teeth	Number of teeth in the AxiGroove.
	Radial Undercut Volume Ratio	Ratio of the radial undercut volume to the whole volume of the AxiGroove.
	Shoulder Diameter A (mm)	Diameter of the shoulder in direction A in millimeters. For external AxiGrooves this is the largest diameter of the turning profile on one side of the AxiGroove. For internal AxiGrooves it’s the smallest diameter. This is -1 for AxiGrooves with no shoulder.
	Shoulder Diameter B (mm)	Diameter of the shoulder in direction B in millimeters. For external AxiGrooves this is the largest diameter of the turning profile on one side of the AxiGroove. For internal AxiGrooves it’s the smallest diameter. This is -1 for AxiGrooves with no shoulder.
	Surface Area (mm²)	Area of all grooves in mm². This is the area of the walls and bottoms of the tooth valleys. It excludes the area of the tooth faces.
	Tooth To Valley Volume Ratio	Ratio of tooth volume to valley volume.
	Valley Axial Extent	Axial length of valley extent in millimeters. This is the total length of all inner faces of the axigroove adjacent to the turnable (recognized) surfaces.
	Volume (mm³)	Volume of axigroove in mm³.
Technique	Requested	The technique selected by you. If you have not selected a technique, this field is set to auto-select.
	Selected	The technique used by aPriori. If the requested technique cannot be used, aPriori will select a technique that can be used.
Results	Time(s)	The time (in seconds) that it takes to machine the GCD or complete work on a technique. If there is more than one occurrence of the GCD or technique, this field shows the sum of the occurrences.
	Status	The costing status of the GCD or technique. A green icon indicates that costing was successful; a yellow icon indicates that costing succeeded with a warning, and a red icon indicates that costing failed.
