This is where you’ll find documentation for some of the projects in the Machine Technology department – both curriculum projects and other fun extracurricular projects.
The Threaded Shaft is your introduction to the lathe. The lathe – with which a stationary cutting tool is brought into contact with a rotating workpiece to produce typically cylindrical shapes – is one of the most common machine tools. You will build upon what you have already learned about print reading, precision measurement, metal cutting operations and tool geometries. You will be introduced to lathe operation, tooling and safety. You will learn how to inspect precision screw threads.
The Angle Plate is your introduction to the milling machine. The milling machine – with which a rotating cutting tool is brought into contact with a stationary workpiece to produce shapes with typically flat surfaces – is one of the most common machine tools. You will build upon what you have already learned about print reading, precision measurement, metal cutting operations and tool geometries. You will be introduced to milling machine alignment, operation, tooling and safety. You will learn how to establish orientation relationships between features and interpret geometric dimensioning and tolerancing on prints.
The Steel Bushings are your introduction to production techniques for the lathe. You will use carbide insert tooling, which ushered in a new era in metalworking in the mid-Twentieth Century with ultra fast cutting speeds, greatly improved ease of use, interchangeability and indexability. You will learn about precision boring on the lathe and some production techniques to manufacture parts efficiently, as well as aligning a workpiece in a four-jaw chuck. You will learn how to inspect surface finish and GD&T for cylindrical parts.
NIMS Mill 2.5 “Step Block”
The NIMS Step Block is a skill-developing exercise on the manual milling machine. You will use many of the skills and techniques you learned in previous projects, including: tramming a milling machine head, squaring up a block, locating and producing holes of different types, and finishing surfaces to achieve flatness, parallelism and perpendicularity. You will learn several new skills, including: using roughing end mills and solid carbide end mills, producing slots and steps, and producing precision holes using an offset boring head and other specialty tools. You will learn how to properly inspect GD&T tolerance of position controls with datum reference frameworks. You will also develop your understanding of the machinist’s thinking process by writing your own project planning worksheet.
Build your own hand scraper for finishing flat surfaces and reconditioning machine tools! If you’re a Laney College Machine Technology student, see your instructor for a free carbide scraper blade.
Machine Tool Alignment Gage
Build your own gage for inspecting the condition and alignment of machine tool way surfaces! If you’re a Laney College Machine Technology student, see your instructor for small components like springs and nuts.
Monochromatic Light Source
Build your own monochromatic light source for evaluating flat surfaces with interferometry! Electrical work should be done only by a licensed electrician.
Graphite Air Bearing
Build your own aerostatic bearing which forces compressed air through porous graphite to ride on a cushion of air! Make a bunch of these and build a fun zero friction device! Get creative!
