Given the function $f(x)=\sin \frac {ωx}{2}\cos ( \frac {ωx}{2}+ \frac {π}{4})-\cos \frac {ωx}{2}\sin ( \frac {ωx}{2}- \frac {π}{4})$ where $x\in R$ and its smallest positive period is $π$.

1. Determine the value of $ω$;
2. Find the maximum and minimum values of the function $f(x)$ on the interval $\[- \frac {π}{4}, \frac {π}{2}\]$.

Present the answer in LaTex format: \boxed{Your answer}
