Parameters of Machinable Hole Feature segments

SolidCAM calculates the values of various parameters for the Machinable Hole Feature segments. These parameters are called HR variables. They will be used later for the technology definition.

Each Machinable Hole Feature segment has the following geometric and visual parameters:

hr_segm_upper_plane

This parameter defines the distance from the Solid Model Origin to the upper level of the Machinable Hole Feature segment (Segment Upper plane).

hr_segm_depth

This parameter defines the distance from the Hole Upper Plane to the lower point of the Machinable Hole Feature segment.

hr_segm_height

This parameter defines the Height of the segment; the distance from the Segment Upper plane to the lower point of the Machinable Hole Feature segment.

hr_segm_color

This parameter defines the variable that can participate in the conditions defined in the Technology Database in order to choose the necessary technological solution. During the conversion of Hole Feature segments into Machinable Hole Feature segments, the RGB color of holes is converted into a number of the Float type and assigned to this variable.

target_color

Before the Hole Features are recognized, the color of the target body is assigned to this variable. The hr_segm_color parameter can be compared with this variable enabling quick access to the color of target.

In addition to the general parameters, SolidCAM determines the following parameters for each type of Machinable Hole Feature segment:

Drill

hr_segm_diameter
hr_segm_height
hr_segm_angle

Chamfer

hr_segm_diameter
hr_segm_angle
hr_segm_lower_diameter

Flat Cylinder

hr_segm_diameter
hr_segm_blind
hr_prev_segm_diameter

Flat Chamfer

hr_segm_diameter
hr_segm_angle
hr_segm_height
hr_segm_lower_diameter
hr_segm_blind
hr_prev_segm_diameter

Thread

Thread Upper level (hr_segm_ upper_plane)
Thread Diameter (hr_segm diameter)
Thread Height (hr_segm_height)
Thread Depth (hr_segm_depth)
Pitch (hr_thread_pitch)

Reaming

Reaming Upper level (hr_segm_ upper_plane)
Reaming Diameter (hr_segm diameter)
Reaming Height (hr_segm_height)
Reaming Depth (hr_segm_depth)

For the Machinable Hole Feature segments containing cylinder (Drill and Flat Cylinder), the Hole Upper Plane is coincident with the Segment Upper Plane. Therefore, the hr_segm_height is equal to the hr_segm_depth.
