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.

Milling Machine Operations
Milling Machine Operations Milling Machine This full article is about milling machine operations. If you haven’t read our complete article on types of milling machine you can read now by clicking here. Let's starts with some little introduction about milling machine and milling machine operations. A milling machine is a machine tool that cuts metal as the workpiece is fed against a rotating multipoint cutter. The milling cutter rotates at a very high speed because of the multiple cutting edges, it cuts the metal at a very fast rate. This machine can also hold single or multiple cutters at the same time. This is why a milling machine has wide application in production work. This is better for other machines as regards accuracy and better surface finish. And also it is designed for machining a variety of tool room work. Milling Machine Operations The 15 different types of milling machine operations are as follow: 1. Plain Milling Operation 2. Face Milling Operation 3. Side Milling Operation 4. Straddle Milling Operation 5. Angular Milling Operation 6. Gang Milling Operation 7. Form Milling Operation 8. Profile Milling Operation 9. End Milling Operation 10. Saw Milling Operation 11. Milling Keyways, Grooves and Slot 12. Gear Milling 13. Helical Milling 14. Cam Milling 15. Thread Milling Read also: Types of Milling Cutters [Complete Guide] TheEngineersPost.com Page 1 Milling Machine Operations Read also: Milling Machine: Main Parts and It’s Working Principle Types of Milling Machine Operations Plain Milling The plain milling is the most common types of milling machine operations. Plain milling is performed to produce a plain, flat, horizontal surface parallel to the axis of rotation of a plain milling cutter. -
Milling Machine a Milling Machine Removes Material from a Work Piece by Rotating a Cutting Tool (Cutter) and Moving It Into the Work Piece
Milling machine A milling machine removes material from a work piece by rotating a cutting tool (cutter) and moving it into the work piece. Milling machines, either vertical or hori- zontal, are usually used to machine flat and irregularly shaped surfaces and can be used to drill, bore, and cut gears, threads, and slots. The vertical mill, or “column and knee” mill, is the most common milling machine found in machine shops today. The general construction of this mill includes the quill, which moves vertically in the head and contains the spindle and cutting tools. The knee moves up and down by sliding parallel to the column. The column holds the Georgia Tech Research Institute turret, which allows the milling head to be positioned anywhere above the table. Hand wheels move the work table to the left and right (X axis), in and out (Y axis), in addition to moving the knee, saddle, and worktable up and down (Z axis). Hazard Serious injuries and entanglement can occur if the operator con- tacts the rotating cutter. Metal shavings and lubricating/cooling fluids might also present a risk from the point of operation area. Material might spin and strike an operator if the material is not secured to the table. Injuries can also occur from a projected wrench if it is left in the spindle. Solution Illinois Institute of Technology Secure the work piece either by clamping it onto the work table or Vertical “column and knee” mill. by clamping it securely in a vise that is clamped tightly to the table. -

Abstract axis of shaft and the vertical axis of end mill cutter are In manufacturing industry there are different types of perpendicular to each other; also the vertical axis of shaft and machining processes are required to convert raw material in to vertical axis of tool are coinciding with each other. final product. Some of machining process required separate machine to carry out machining of product. It means not only consumption of space and overall time increases but also expenses will increases. By developing the special attachment for machine will reduces consumption of time and space. Various operations like Turning, Drilling, Facing, slotting will be done on single machine. Instead of milling machine we are using the special attachment for lathe machine to machining of key way slot. In thispaperdiscussed aboutthemilling attachment for lathe machine through whichwe eliminated cost of slotting and milling. Machine operates through lathe machine. It consist of lathe machine slide, electric motor, power chuck, end mill cutter, dowel pin etc. Keywords:lathe machine, milling operations, end mill cutter, lathe machine slide, key way.
