G107

[rajeshtikar]

Can any body post an example program using G107 on Horizontal Machining Center with Cutter Compensation.

[JWK42]

Here is an example of a part we do on our Haas Hortizontal. The 'X' axis moves become 'A' axis moves and the 'Y' axis moves stay linear. The R word in N150 tells the control the radius of the part where the 'X' to 'A' conversion takes place. The example in the Haas mill manual explains it fairly well.
