2020 3 10 nbsp 0183 32 We use a drilling macro that creates toolpaths dependent on the feature set size and depth The feature sets do need to be separated by size and depth for it to work We just select all the feature sets you want to create drilling toolpaths for and run the macro As G83 is a Peck drilling cycle so the depth for each peck in G83 drilling cycle will be the amount defined with Q The tool will take the peck Q deep Then the tool will rapid up to the R plane after each peck and then back in for the next

2015 2 13 nbsp 0183 32 I have to drill very deep holes up to 12 inches I start with a 4 quot drill then an 8 quot and finish with a 14 quot I would like to start the longer drills at the depth that the previous drill finished but I can t get the peck to retract to the top of the part For example if I use my 4 quot drill to a depth of 3 5 quot then start my 8 quot drill at 3 45 quot my 8 quot drill will retract between pecks to 3 45 quot 2018 8 21 nbsp 0183 32 N50 Coolant ON N60 Return to R plane in canned cycle Peck drilling cycle command Depth of drill is 55 R plane distance is 5 depth of each cut is 20 incremental feed rate per minute is 300 N70 Tool is return at intial position cancel canned cycle rapid command where tool is 100 mm up along z axis

2001 6 1 nbsp 0183 32 An example of a variable peck cycle is one starting with a 1 00 inch peck The next peck would only go 0 50 inch deeper followed by one 0 25 inch deeper with the last peck going only 0 05 inch deeper than the previous peck As the drill goes deeper into the hole the decreasing peck depths help eliminate chip impaction around the tool 2008 11 5 nbsp 0183 32 When peck drilling say a 3 8 quot hole in 6061 what feed rate peck depth and retract depth would be appropriate I ve been using about 5IPM 1 8 quot peck 0 05 quot retract That still results in some pretty good quot strings quot and drilling holes takes quite a while
