![]() ![]() (The Z position is assumed to be already given in the program at a previous point) G00 X19.0 moves the tool into the start position to machine the 45 degrees chamfer at the front of the part. N defines the first line of the subroutine, the following code is the profile of the part that we wish to cut. Q200 tells the machine to stop reading the subroutine when it reads Look for N100 and start reading from that point. We state the beginning of the subroutine profile that we wish our roughing tool to follow, P100 tells the controls to This first line tells us that we are taking 1.0mm cuts (U) and the tool is retracting 1.0mm after each cut (R) The 'U' on the second G71 line tells the machine the amount we wish to leave on for a finishing pass in X while the 'W' is the finishing allowance in Z. In the above example, 'P' would be P100 and 'Q' would be Q200 so they match the 'N' numbers. These values can be any 3 digit value as long as it matches the 'N' numbers of the subroutine. The 'P' and 'Q' values define the start and end point of our subroutine respectively. The R refers to how far the tool will retract from the part in X when returning in rapid to the start of the cycle. The U on the first line of code is the depth of cut of each roughing pass. G71 is our G-Code that lets the controls know that we wish to use a roughing cycle and that the following They come in come in work capacities of 14” x 40” to 22” x 120”, spindle bores of 1.5” to 3.582”, and up to 15 HP of spindle motor.Before we look at an example program of the G71 roughing cycle, let's take a look at the G71 line of G-Code and what each part does.īelow is a brief explanation of how we can control this cycle.įeel free to download the infographic here as a The Kent USA CNC Precision Teach Lathes Series is available for the more precision demanding workpieces.
