Cutting tools can be divided into single-point tools, commonly used on the lathe, and multi-point tools, commonly used in milling and holemaking. The shape and type of chip created by cutting indicates whether or not cutting conditions are optimized. Adjusting tool angles and cutting variables has the largest effect on chip creation and cutting conditions.Understanding how chips are formed and what factors change or optimize chip formation is essential to performing an effective metal cutting operation. Chip formation affects surface finish, part quality, and tool life, and thus has a large effect on manufacturing economy.
Summary: "Band Saw Operation" gives an in-depth description of the considerations required for band sawing operations. Band sawing is a common way to perform rough cuts on raw stock, and uses a continuous, flexible metal blade looped over machine wheels. Band sawing can be performed with a variety of blade materials and styles, including different tooth spacing and geometry. The specific blade type and cutting variables used depend on the specific workpiece and cutting operation.Band sawing can be an efficient, low-cost way to rough cut stock to size. However, in order to effectively perform band sawing operations, operators must be aware of factors such as blade material, tooth set, tooth form, tooth spacing, and optimal speed and feed settings. This class provides the information necessary to identify optimal band sawing variables and conditions.
Summary: "Introduction to Metal Cutting Fluids" provides an overview of the use of cutting fluids in machining operations, including basic fluid safety and maintenance. Appropriate cutting fluid selection depends on the specific cutting operation and workpiece material, among other factors. Basic types of cutting fluids include various combinations of oils, water, and chemicals. Each type is classified by its contents. After explaining the basic function of cutting fluid, the class describes each category of fluid and its benefits and drawbacks.Appropriate cutting fluid use and maintenance are key factors in the success of a cutting operation. Proper cutting fluid application can prolong tool life and improve finished part quality, reducing scrap and tool cost. Awareness of cutting fluid hazards and maintenance helps increase workplace safety and reduce fluid costs. After taking this class, users will be able to identify the common types of cutting fluids and describe their optimal use.
Summary: "Speed and Feed for the Lathe" provides a thorough explanation of cutting variables for lathe operations, including how these variables are measured, selected, and set. Many variables affect speed and feed selection, especially the type of cutting operation, tool material, and workpiece material. The class covers speed and feed selection for both manual and CNC machines.The proper selection of speed and feed is necessary to maximize tool life, productivity, and surface finish. Understanding cutting variables reduces tool wear, damage to machine components, and scrapped parts.
Summary: "Speed and Feed for the Mill" provides a thorough explanation of cutting variables for mill operations, including how these variables are measured, selected, and set. Many variables affect speed and feed selection, primarily the type of cutting operation, tool material, and workpiece material. This class covers speed and feed selection for both manual and CNC machines.The proper selection of speed and feed is necessary to maximize tool life, productivity, and surface finish quality. Without an understanding of cutting variables, tools will wear prematurely, machine components will sustain increased wear and tear, and the number of scrap parts produced will increase.
Summary: Application of the techniques presented in this program will improve your machining process efficiency by at least 20%. These techniques have delivered four-fold increases in tool life, elimination of scrap, and increases in profitability. It enhances manufacturing efforts in all Lean enterprises.
Summary: The purpose of this program is to provide a standard achievement to improve participants’ knowledge and understanding of metalworking fluid management. Beginning with a review of the many different operations that use metalworking fluids, the program covers everything from the fundamentals of fluid and additive chemistry to end-user troubleshooting. Once participants pass the post-exam, they will have documentation to validate their expertise.
