Some photos of your machines spindle head might help us to determine what you do and do not have.

Download this program and run the code through it with the scale set at 0.9.

On the main screen you have scale entries next to the position dro,s click one of them and enter 0.9 and hit enter do this on both X & Y axis.

SolidCAM is the product that integrates with Solidworks so that would be a good starting point.

« on: July 11, 2011, 07:35:07 PM »

To do a simple loop you can do this :-

%
O0001 (MAIN PROGRAM)

G21 G40 G80 (STANDARD SETUP LINES, METRIC, CLEAR OFFSETS, CANCEL CANNED CYCLES)

N1 (TOOL 1)
G54 (SELECT FIXTURE OFFSET 1)
T1 M6 (SELECT TOOL 1)
G00 G90 G43 X0 Y0 Z25. H1 S2000 M3 (RAPID 3 AXIS MOVE TO START POINT IN ABSOLUTE AND START SPINDLE)
Z1. (RAPID 1MM ABOVE JOB)
G01  Z0  F150. (FEED TO TOP OF JOB)
X25. F200. (FEED OUT TO 25MM)
M98 P0002 L20 (CALL SUB PROGRAM O0002 20 TIMES)
G00 G90 X0 Y0 (RAPID TO CENTRE OF CIRCLE IN ABSOLUTE MODE)
Z0 (RAPID CLEAR OF JOB)
M30

O0002 (SUB PROGRAM)
(THIS SUB IS CALLED 20 TIMES FROM MAIN PROGRAM)
(BECAUSE IT IS IN INC MODE THE TOOL WILL MOVE Z-1MM EACH PASS AND CREATE)
(A HOLE 50MM DIA + TOOL DIA TO A DEPTH OF 20MM)
G91 (CHANGE TO INCREMENTAL)
G01 Z-1. F50. (FEED DOWN 1MM)
G03 I-25. F150. (MOVE IN A CCW CIRCLE)
M99
%

Once all the remarks are removed the code is very compact and easily changed to alter the bore size.

One thing to remember is that the L command has a range of 0 to 99.

Hi Deano,

what is it you want to know, give me a clue as to what you want to do and I will try and explain it in simple terms, to write a whole document would take way too long but snippets of code I can do.

what size cutters have you got and where is your datum point?

In hard materials you need to be above 20,000 rpm and the feed should be no more than 1/4 the tip dia per rev and depth of cut 1/3 tip dia.

I have had good results based on this but the machines are also very rigid so only a guide.
