The number of flutes on a bit is essential to calculating proper feed and speed rates.For most applications you can use a bit with 1, 2, or 3 flutes, but you must adjust your reed rates and RPMĪccordingly to maintain proper chip load. Next we will go through each parts of the machine. The X,Y and Z axesĪre marked in the picture, the bed is having the dimension of 96X48 inches in X and Y directions and Z is 6 inches. ShopBot PRS alpha 96X48 in our lab is shown below. Inorder to Start working with shopbot, first we should know about the parts of the machine and operation of each. You SHALL NOT work alone while in the SpaceShop.You SHALL NOT wear or have any loose objects on your body while operating this machine.You SHALL NOT touch materials and chips being cut since they can be hot.You SHALL NOT leave a machine unattended while in operation.ou SHALL use your sense of sight and sound to keep yourself aware of the operational conditions of the ShopBot for safe use.You SHALL ensure the End Mill is fastened securely inside the spindle collet, before starting your operation.You SHALL always use a sacrificial layer under the material you are cutting, so as not to cut into the table below.You SHALL make sure the spindle collet and cover nut are properly secured and not over-tightened.You SHALLalways be ready to react in case an operation fails.You SHALL make small cuts at slow speed otherwise you will risk breaking the cutting tool, and ruining your material.You SHALL secure badge and any loose items that might get caught in moving machinery.You SHALL wear eye protection when working with tools and processes that involve wood chips or sawdust.You SHALL wear closed-toe shoes at all times.You SHALL wear ear protection while working.Shopbot is one of the dangerous machines in Fab lab and we must take some safety precautions while working with it, here I am noting some safety precautions that i got from one documentation. Easy to configure and re-configure, learn and use, the PRSalpha CNC delivers affordable,įull-production performance in digital fabrication of wood, plastic, foam and other materials. ![]() The ShopBot PRSalpha delivers rapid transit speeds of 1800 inches per minute and cutting speeds of up to 600 inches per minute. The shopBot we are using is PRSAlpha 96X48 ,96X48 is its Gantry size ShopBot can perform precision, large format, cutting, drilling, machining, and shaping in many materials and isĬontrolled by a standard personal computer. ShopBot PRSalpha CNC is a is a low cost, computer numerically controlled router (CNC Router) These are the sites having good collection of designs.īefore starting the design will know about the machine its operation,specifications,workflowĪre important, we have to design by considering all these things. I have identified Rhinoceros software to design the 2D designs, surfed many sitesĪnd finally decided to make a stand for Roland Vinylcutter ![]() This week we have to design something big using 2D or 3D design softwarsĪnd process it using CNC Machine, here in our lab the CNC machine available is Shopbot PRSĪlpha.
