Select the vector, then open the Tool Database dialog and create a new tool. These values are defined for a particular material / machine. Oh yeah, I use Vcarve Pro. it seems as if the bit does not fully come up out of the cut before the X and Y axis begins to move and ultimately snaps the bit because it clips the uncut portion of the material . Thank you all for your input. Tool: 1/32" flat end mill Feed rate: 23.62 in/min (600 mm/min) Plunge rate: 1.575 in/min (12 mm/min) Spindle speed: 12,000 RPM When using V-Bit Tools, the Stepover fields automatically change to use the following options. Overwrite: When it's faced with two similarly nested tools that have the same tool geometry, the cutting data of the incoming tool will overwrite the current tool's cutting data for the active machine / material. When a tool or group is selected in the Tool List, its properties are displayed in the Tool Info section on the right-hand side of the Tool Database. Feed rate. Login to the portal to be able to access the currently stored tool database and / or upload your existing local one. Import: This will simply import the given tools under the selected group (or as a top-level tool / group). My question to the masses is Iâve broken 2 bits when carving. It is important not to plunge too fast as it is easy ⦠Without overwriting: A new machine / material will be created to contain the cutting data of the incoming tools. This is the height above the job at which it is safe for the cutter to move at rapid or maximum feed rate. So changing the plunge rate will have no effect. And yes @BobJewell .5 was overkill so I tweaked it a bit to increase my carve times and found suitable heights for the various material thicknesses. The selected geometry will be imported and a profile displayed in the window. Tool geometry entities (organised hierarchically in the tree). I donât know VCarve, but most CAM software have a setting for safe hight. This is accomplished by changing the Image height property. The Plunge (Z2) is an added feature. The name displayed here is then a result of evaluating the template in the current context (active machine, material and the cutting data defined for those as well as the tool geometry). The units can be specified in distance per second or per minute. Dell optiplex 5070 hackintosh. This can be used for when we know there is a more up-to-date version online. Material Endmill #Flutes RPM Feedrate (mm/min) Depth of Cut Plunge Rate (mm/min) Beech: 6mm square: 2: 12000: 1905: 1mm: 476: Beech: 3.175mm square: 1: 12000: 425: 0.7mm These values may not be set for your machine capabilities. The maximum depth of cut the tool can cut. Change the Feed Rate and Z Safe values to values that are suitable for your machine and material. Sounds like maybe Z step loss when moving up. I use 40% for roughing, 10% for finishing. The cutting rate at which the cutter is moved vertically into the material or during ramping moves. For most woods, I usually set the Plunge Rate to 10 mm/sec or less. The tool database can be stored and linked to your portal account so that it can be retrieved at any point from a different installation. Regardless of plunge rate Z will retract to its safety height before any X&Y changes are done. The tool image will indicate where this dimension is taken from. This is the calculated Chip Load based on the entered values for the Number of Flutes, Spindle Speed and Feed Rate. Plunge Rate: 50 Inches Per Minute Speed (RPM): 8,000.
