In a CNC Machine functions and slide movements are controlled by motors using computer programs.
11. • By integrating a computer processor, computer numerical control, or “CNC” as it is now known, allows part machining programs to be edited and stored in the computer memory as well as permitting diagnostics and quality control functions during the actual machining. • All CNC machining begins with a part program, which is a sequential instructions or coded . 6. • Base of both milling machines supports the entire machine. • Column also a structural member which houses the knee, spindle, bearing, gear box, clutches, shaft, pumps, power transmission mechanism for motor to spindle, etc. • Knee mounted in front of the column is for supporting the table and to provide an up or down motion along the Z axis. 3. INTRODUCTION • EDM is a machining method typically used for hard metals which are electrically conductive. • It makes possible to work with metals for which traditional machining techniques are ineffective. • The use of a thermoelectric source of energy in developing the nontraditional techniques has greatly helped in achieving an economic machining of the . CNC Turning.ppt - Download as a PDF or view online for free. Submit Search. . All CNC machining begins with a part program, which is a sequential instructions or coded commands that direct the specific machine functions. • The part program may be manually generated or, more commonly, generated by computer aided part programming systems. 5 .
14 CNC Motions CNC machines move their axes in five ways: Rapid Travel Linear single or multi axis straight line motion Circular motion within a single plane. Circular/Linear, also called 2 ½ dim. motion. Two axes move in an arc while the third moves in a straight line. 3-D motion few controls have the ability to move in an arc using 3 axes simultaneously. 3. CNC MACHINING The use of computers to control machine tools Tools include lathes, mills, drills and grinders. Machine tools function through numerical control A computer program is customized for an object and the machines are programmed with CNC machining language (called G-code) Controls all features like feed rate, coordination, location and speeds 3

5. 18 MAINTENANCE A. PREVENTIVE MAINTENANCE Many of the service problems that occur over the lift of any Machine tool can be avoided through the application of proper Preventive maintenance practices. The purpose of this section Of the manual is to help you in setting up a regular schedule of Periodic preventive maintenance measures for your CNC lathe. Keeping . The CNC Machining is an Computer Numerical Control (CNC) machines are automated milling devices that make industrial components without direct human assistance. They use coded instructions that are sent to an internal computer, which allows factories to fabricate parts accurately and quickly. There are many different types of CNC machines . CNC machines operate based on coded instructions to control machine tools. A CNC system includes a part program, program input device, machine control unit, drive system, machine tool, and feedback system. CNC machines can move tools in either a point-to-point or continuous path manner and use either open or closed loop control systems. Features of CNC For a CNC machine control unit (MCU) decides cutting speed, feed, depth of cut, tool selection , coolant on off and tool paths. The MCU issues commands in form of numeric data to motors that position slides .
Introduction CNC milling machines perform same functions as manual, and creates arcs, contours and 3D surfaces FIGURE CNC milling machines can produce complex part surfaces that would be virtually impossible to produce with manual milling machines. Photo courtesy of Haas Automation, Inc.
To start with, CNC machining centres were developed for machining prismatic components combining operations like milling, drilling, boring and tapping. Gradually machines for manufacturing cylindrical components, . 11. is the direct interface between operator and the NC system, enabling the operation of the machine through the CNC system. Fig shows the MCP of Hinumerik 3100 system. • • During program execution, the CNC controls the axis motion, spindle function or tool function on a machine tool, depending upon the part program stored in the memory. Deccan Engineering Works is India’s Leading CNC Machining and CNC Turing expert Company. CNC Turning is an assembling procedure in which bars of material are held in a throw and pivoted while a device is sustained to the piece to expel material to make the coveted shape. A turret (indicated focus), with tooling connected is modified to move .Milling and Turning is widely used to machine engineering-grade plastic and metal parts to produce prototypes. CNC machining usually refers to high precision parts machining, CNC lathe machining, CNC milling multi-axis machining and so on. CNC machining works well for smaller quantities of up to 100+ parts process.
2. Introduction • In laser cutting and drilling, the focused laser beam is directed onto the surface of the work piece to rapidly heat it up, resulting in melting and/or vaporization, depending on the beam intensity and work piece material • Lasers can be used to effectively cut metal plates of thicknesses up to about 10 cm. The cut surfaces are roughly parallel and . 11. Advantages of CNC • Flexibility of operation is improved, as is the ability to • Produce complex shapes with good dimensional accuracy, • Repeatability, reduced scrap loss, and high production rates, • Tooling costs are reduced, since templates and other fixtures are not required. • Machine adjustments are easy to make with microcomputers • More operations can .
6. 6 EDM is a machining method primarily used for hard metals or those that would be very difficult to machine with traditional techniques.
