Course DescriptionCovers setup, applications, parts and operation of the sensitive, upright and radial arm drill presses. This course introduces the commonly performed operations of drilling, reaming, counterboring, countersinking, spot facing and tapping on the various types of drilling machines used to produce part features to print specifications. Prerequisites: MCH 100, 125, 135. Audit available.
Intended Outcomes for the course
The student will be able to translate information from blueprints and safely perform many of the operations capable of the sensitive drill press and radial arm drill press, including drilling, reaming, counterboring, spotfacing, countersinking, and hand and power tapping.
- Accurately list and calculate the proper speeds for the tools used in this course.
- Accurately set up and perform the following operations on a single work piece according to the print specifications:
- Drill, ream, counterbore, spot face, countersink, hand tap and power tap.
- Accurately lay out a work piece according to the print specifications, calculate proper speeds and feeds, and perform the following operations on the radial arm drill press.
- Drill and power tap.
Course Activities and Design
MCH 160 will be presented by means of audio-visual presentations, demonstrations, lab experiences, and research activities. The course activities and design emphasize the development of skills and knowledge outcomes prescribed by established industry standards. The identified outcomes will be achieved by means of individual and team activities.
Outcome Assessment Strategies
Course Content (Themes, Concepts, Issues and Skills)
Drilling on the Drill Press - Holes are often machined in a work piece by using a drill mounted in a drill press. In this module, the student will learn to drill holes in a work piece on the drill press.Reaming on the Drill Press - Holes are often machined in a work piece to an accurate size and smooth finish by using a reamer mounted in a drill press or by hand. In this module, the student will learn to ream holes in a work piece on the drill press and by hand.Counter Boring/Spot facing/Counter Sinking on the Drill Press - The head of a cap screw or nut can be seated properly only if the mating surface is flat or cone shaped. Whether the mating surface is exposed or recessed, the machinist must insure that it is flat or cone shaped by countersinking or counterboring (for recessed surfaces) or spot facing (for exposed surfaces). Spot facing is done around the hole to provide seat for the screw head or nut; counterboring produces a square shouldered hole or recess on an already existing hole. Countersinking produces a cone shaped surface around an already existing hole to accept a flat head bolt or screw. In this module, the student will receive instruction in and an opportunity to practice counterboring.Hand Tapping - In this module, the student will receive instruction on hand tapping on the drill press.Power Tapping - When a large number of drilled holes are to be tapped, the machinist uses the drill press. In this module, the student will learn the proper steps and how to power tap with the drill press.Radial Arm Drill Press - The Radial Drilling Machine, sometimes called a radial-arm drill, has been developed primarily for the handling of larger work pieces and drilling tools than is possible on upright or sensitive drilling machines. In this module, the student will learn to operate the radial arm drill press.
