Hole and countersink measurement system

A hole measurement system comprising:

• a housing;
• a countersink measurement system associated with the housing in which the countersink measurement system comprises:
• a tip configured to engage a countersink for a hole, in which the countersink measurement system is configured to measure a diameter of the countersink for the hole when the tip is engaged with the countersink and in which the tip of the countersink measurement system is a structure having a conical shape;
• a biasing mechanism configured to bias the tip of the countersink measurement system in a first direction along an axis, wherein the tip of the countersink measurement system is in a first position when the tip is not engaged with the countersink and in a second position when the tip of the countersink measurement system is engaged with the countersink;
• and
• a number of sensors configured to measure a movement of the tip of the countersink measurement system along the axis from the first position to the second position;
• a diameter measurement system associated with the housing in which the diameter measurement system is configured to measure a diameter of a channel for the hole about every 0.0005 inches and comprises:
• a probe, in which the diameter measurement system is configured to move the probe through the tip of the countersink measurement system in a first direction along the axis into a first end of the channel towards a second end of the channel when the tip of the countersink measurement system is engaged with the countersink, rotate the probe about the axis, move the probe in a second direction along the axis back out of the first end of the channel after rotating the probe, and measure a number of diameters for the channel while the probe moves in at least one of the first direction and the second direction;
• a carriage in which the probe is associated with the carriage;
• a motor configured to move the carriage along the axis;
• a number of rods, wherein the carriage is configured to move along the number of rods and the axis;
• a ball screw connected to the motor and the carriage, wherein operation of the motor turns the ball screw to cause the carriage to move along the number of rods and along the axis;
• and
• a rotational motor configured to rotate the probe about the axis;
• a processor unit configured to control operation of the countersink measurement system and the diameter measurement system;
• receive data for the diameter of the countersink and the number of diameters for the channel;
• and generate an indication of whether the hole meets a requirement for the hole using the diameter of the countersink and the number of diameters measured for the channel.

A method for measuring diameters of holes, the method comprising:

• moving a tip of a countersink measurement system to engage a countersink for a hole;
• measuring a diameter of the countersink in response to the tip of the countersink measurement system engaging the countersink;
• moving a probe through the tip of the countersink measurement system into a channel for the hole while the tip is engaged with the countersink;
• and
• measuring a number of diameters for the channel as the probe moves in the hole.

• moving a probe through the tip of the countersink measurement system into a first end of a channel for the hole in a first direction along an axis extending through the tip of the countersink measurement system towards a second end of the channel while the tip is engaged with the countersink;
• rotating the probe about the axis;
• moving the probe in a second direction along the axis towards the first end of the channel;
• measuring a number of diameters for the channel as the probe moves in the channel;
• and
• generating an indication of whether the hole meets a requirement for the hole using the diameter of the countersink and the number of diameters for the channel.
