Metal Lathe Safety West Virginia University Environmental Health and Safety Pre-Use Activities . Review and understand information provided in the metal lathe operator’s manual with particular attention given to descriptions of safety procedures. Inspect the metal lathe for damage, disrepair, or missing parts, including assessing whether any shear pins are broken. Make sure all shields and guards are securely in place. If a metal lathe fails the pre-use inspection, notify your supervisor and remove the lathe from service by attaching a red tag that states “OUT OF SERVICE”. Complete red tag with appropriate information. Operating Precautions . Wear safety glasses with side protectors when using a metal lathe. Never wear gloves, a tie, loose clothing, a watch, rings, or jewelry when using a metal lathe. Tie long hair back or secure under a cap. Determine that the work piece is properly centered and securely clamped in the chuck. Remove the chuck key from the chuck before starting the metal lathe. Keep metal lathe cutting tools sharp. Do not use damaged or broken metal lathe cutting tools. Center drill the work piece and use a live tail-stock for stability when the work piece is turning. Keep your hands and fingers away from metal lathe moving parts and cutting tools. Follow recommended specifications for speeds of rotation and feed and depth of cut for the metal being turned. Assure the adjustment for the cutting tool and tool rest is set slightly above the center of the work piece. Do not measure work or attempt to adjust a chuck or work piece while it is rotating. Start the metal lathe at a slow speed and then gradually increase the rotational speed. Never reach across the rotating chuck or work piece while performing filing or burnishing operations. Back the cutting tool away from the metal being turned and then turn off the metal lathe before adjusting or removing a work piece. Do not use your hand to brake or stop a rotating chuck. Clean the metal lathe work area. Use a brush, rather than your fingers or hands, to sweep up waste metal shavings and cuttings. Disconnect the power source before performing metal lathe maintenance..

CNC Application and Design
CNC Application and Design by Patrick Collins, Charles Cummings, Wesley Dittrich, Paul Jones, Andrew Sealey Major Qualifying Project Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE In partial fulfillment of the requirements for the Degree of Bachelor of Science in Mechanical Engineering ___________ _____________ _____________ Patrick Collins Charles Cummings Wesley Dittrich _____________ _____________ Paul Jones Andrew Sealey APPROVED: APRIL 2011 _______________________________ Professor M. S. Fofana, Major Advisor Mechanical Engineering Department Abstract Machining is an important manufacturing process that is used in a wide range of applications. From aerospace applications to the manufacturing of energy systems and medical robots, we see a major reliance on machining. In this project we focus on gaining an improved understanding of the mechanics of machining and the different factors that contribute to part quality. We acquired primary machine shop skills that provided us an opportunity to mill and drill a class of components to specified dimensions and tolerances. For each component, we created a detailed engineering working drawing that helped to shape and construct all the operations and procedures that must be undertaken and controlled to attain component machining without any breakdown or failure. Through hands-on machining, we discovered many different factors involved in milling, drilling, and the effects they exhibited on the tolerance and surface finish of a part. The main relevant factors that we examined were tool selection, speeds, feeds, and material selection. The extent to which these factors can influence machining is presented. The MQP project establishes new ways to systematically perform machining in a safe and stable manner without impacting the quality of the surface finish.
