mplfan G02/G03

[PROG_MAN_DO]

I am using the mplfan.pst and the G02/G03's are coming out opposite of what they should be. Any suggestions. The X and Z values are good so that tells me we have the turret spindle orientation correct..I did have to change the dia_mult to -2 to change the sign of X..whazzupp??

 

thanks in advance

Just taking a guess here... What does it say when you backplot? Check it in isometric view to make sure the tool is not entering from the opposite side of the workpiece. Basically are you in the correct tool plane? Are you using WCS and you got the wrong one?

Oooops, I was thinking mill. Don't know nothing about lathe... Sorry

I just tried a sample with the Fanuc post and it worked right. Try another post to see if you get the same results. If so, something is strange in your toolpath. If not, something else was changed in your post.

We did try another post and it came out correct.. what now?

Russ,

If you had to change dia_mult to -2 then this tells me that you are running a machine that uses X- (minus)

You need to change your settings for g02/g03 to output correctly.

look for this in your post:

Notice how the g03 is g2 and g02 is g3?

You need to make these changes in order to post right.

Buckethead is correct and what he suggests will work. MPLFAN is setup to support many different configurations. We have a section in the post that you can set to control the different settings of the machine configuration such as the signs of XYZ, Arc and Comp direction, Spindle and plane direction as well as the C axis configuration. By changing these strings you can accomplish the same thing and actually have more control when needed. These are shown below.

 

code:

---

#Machining position turret/spindle settings

# Switch strings based on turret position top/bottom-left/right and cut type.

# Turret position is based on the Mastercam settings (see lathtype).

# Strings are re-assigned for output in the routine psw_str_mult.

# The string variable sw_string holds the place position value to determine

# how to assign the strings. Planes are relative to the view from Mastercam.

# Assign the 17 digit string following the alpha columns below:

# A - C axis, 1 = axis winds, 2 = axis signed, 3 = indexer

# B - Spindle direction, 0 = normal, 1 = reverse

# C - Plane 0 arc/comp, 0 = normal, 1 = switch

# D - Plane 1 arc/comp, 0 = normal, 1 = switch

# E - Plane 2 arc/comp, 0 = normal, 1 = switch

# F - Plane 0, 0 = G17, 1 = G19, 2 = G18

# G - Plane 1, 0 = G17, 1 = G19, 2 = G18

# H - Plane 2, 0 = G17, 1 = G19, 2 = G18

# Decimal (required)

# I - Plane 0, X axis, 0 = normal, 1 = switch sign from basic

# J - Plane 0, Y axis, 0 = normal, 1 = switch sign from basic

# K - Plane 0, Z axis, 0 = normal, 1 = switch sign from basic

# L - Plane 1, X axis, 0 = normal, 1 = switch sign from basic

# M - Plane 1, Y axis, 0 = normal, 1 = switch sign from basic

# N - Plane 1, Z axis, 0 = normal, 1 = switch sign from basic

# O - Plane 2, X axis, 0 = normal, 1 = switch sign from basic

# P - Plane 2, Y axis, 0 = normal, 1 = switch sign from basic

# Q - Plane 2, Z axis, 0 = normal, 1 = switch sign from basic
