Milling Machines and Cnc Mills
MILLING MACHINES AND CNC MILLS Safety Precautions MILL SAFETY HAZARDS Milling machines and computer-numerical-controlled (CNC) mills use moving cutters and/or move stock materials to cut shapes materials such as metal, wood or plastic. Mills cut away material using rotating blades, and can throw or eject dust and chips at high speed. Flying chips present an eye injury hazard. Fine dust can be a respiratory hazard. Mills can also be very loud, presenting a threat to hearing as well as drowning out voices, phones, and alarms. Rotating machinery presents a serious hazard, as gloves, clothing, jewelry or loose hair can be caught and body parts drawn into the running machine. Mills have guards to prevent some exposure, and some are completely enclosed when running. • Keep hands, tools, and clothing at least 12 inches away from the moving mill and do not SAFETY PRECAUTIONS attempt to adjust the mill while operating. • Wear safety glasses or goggles, and hearing Safety rules include: protection if needed. Do not wear gloves near • Get trained on the operation of the specific mill operating equipment. you are going to use. • Keep the mill surfaces and shop floor clean of • Never work alone, never leave the milling cuttings and dust. Metal filings can combust machine unattended while running, and know spontaneously and require a Class D fire where the emergency stop controls are located. extinguisher. • Securely clamp the stock material in place. • Secure guards, shields, doors in place prior to Machinery must be completely disconnected from starting. power (and tested) if it is to be repaired or adjusted (see the Hazardous Energy Control page).

Manufacturing Processes
Module 1 Classification of Metal Removal Processes and Machine tools Version 2 ME IIT, Kharagpur Lesson 2 Basic working principle, configuration, specification and classification of machine tools Version 2 ME IIT, Kharagpur Instructional Objectives At the end of this lesson, the students should be able to : (a) Describe the basic functional principles of machine tools (i) Illustrate the concept of Generatrix and Directrix (ii) Demonstrate Tool – work motions (iii) Give idea about machine tool drives (b) Show configuration of basic machine tools and state their uses (c) Give examples of machine tools - specification (d) Classify machine tools broadly. Basic functional principles of machine tool operations Machine Tools produce desired geometrical surfaces on solid bodies (preformed blanks) and for that they are basically comprised of; • Devices for firmly holding the tool and work • Drives for providing power and motions to the tool and work • Kinematic system to transmit motion and power from the sources to the tool-work • Automation and control systems • Structural body to support and accommodate those systems with sufficient strength and rigidity. For material removal by machining, the work and the tool need relative movements and those motions and required power are derived from the power source(s) and transmitted through the kinematic system(s) comprised of a number and type of mechanisms. (i) Concept of Generatrix and Directrix • Generation of flat surface The principle is shown in Fig. 2.1 where on a flat plain a straight line called Generatrix (G) is traversed in a perpendicular direction called Directrix (D) resulting a flat surface. • Generation of cylindrical surfaces The principles of production of various cylindrical surfaces (of revolution) are shown in Fig.

DS10524_Lathe_Tooling_0921B TORMACH.COM Tormach® CNC Lathe Tooling REFERENCE GUIDE To make the most of a machine purchase, it’s important to understand how cutting tools work and which inserts they pair with. Here is some background on lathe cutting tool and insert terminology: ISO/ANSI Inserts Like metric and imperial measurements standards, the U.S. has its own tool TABLE OF insert classification system; they are called American National Standards Institute (ANSI) designations. All of these ANSI classifications can be converted CONTENTS to the International Organization for Standardization (ISO) classifications, but this guide includes both for easier selection. Cutting Tool Designations 3 Turning Tools Cutting tools are easily identified by their designation, which is universal between ISO and ANSI, and, in the machine shop, tool slang often refers to 6 Boring Bars the insert shape, which is also available in the tool designation. Examples and explanations of designations are available at the start of each section. 7 Turning/ Boring Right-Hand vs. Left-Hand vs. Neutral Inserts Right-hand tools are the most commonly used, because they can be used for most turning applications, including making shoulders on the front of the workpiece. Left-handed tools are typically chosen for back turning and making 11 Grooving/ Parting sharp shoulders on the back of the workpiece. Neutral tools are ideal for Tools complex profiling, thanks to their narrow tips. Insert Shapes 12 Grooving/ Parting There are a variety of insert shapes available, but the general note is use Tool Inserts wider inserts for simple geometry and roughing passes, since they have more durability than a more narrow cutting tool, which is needed for complicated or 12 Threading Tools intricate parts.

Validation of Thermal Errors Compensation Models for Different Machine Tool Structures Via Test Pieces
Validation of thermal errors compensation models for different machine tool structures via test pieces Otakar Horejš, Martin Mareš, Lukáš Havlík 1. Introduction 3. Six-spindle automatic lathe Although real-time software compensations of thermal errors exist, The test pieces can be also employed for the evaluation of the majority of these models are not sufficiently validated in real machine tool thermal errors. This application is illustrated on a six- finishing operations using a test piece. The accuracy and spindle automatic lathe. The basic scheme of the test piece, robustness of the developed models are mostly examined using manufactured by a specific technology, is depicted in Figure below. non-cutting measurements. In contrast, machining tests can be more intuitively understood to evaluate the machine’s accuracy for typical machine tool users. Moreover, the machined test piece represents a suitable method to verify thoroughly the industrial applicability of the developed thermal errors compensation model for machine tool builders. The paper presents the authors’ recent research on these issues. Specific test pieces for different machine tool structures are illustrated (test pieces for a gantry-type 5-axis milling centre with a rotary table, a six-spindle automatic lathe and a vertical turning lathe). 2. Gantry-type 5-axis milling centre The test piece material was an aluminium alloy covered with an The diameter denominated as D1 of the test piece is manufactured eloxal coating for better visibility of cutting tool imprints on the at the first machining position (MP), the diameter denominated as surface caused by thermal error at the TCP in Z-direction.
